The Myra Falls mines are located in the Strathcona provincial park in the Myra Valley on Vancouver Island, British Columbia, Canada. Situated approximately 90km southwest of the coastal town of Campbell River, the property comprises the H-W and Battle-Gap underground mines, producing zinc, copper, gold and silver. The operation employs around 440 people. Production was previously sourced from the Lynx open pit and the Myra and Lynx underground mines, all of which are now closed.
Myra Falls was originally owned by Westmin Resources, which was later bought by the Swedish company, Boliden. Having unsuccessfully sought to sell the mines during 2001, Boliden closed them temporarily while developing a new mining plan. After re-opening in 2002, the 20% cost reduction achieved made the operation profitable. In mid-2004, New Boliden sold the operation to the Canadian company, Breakwater Resources, for $12.5m in shares and options, plus the assumption of environmental liabilities.
The mines are located in a stratigraphic sequence of volcanic rocks over 6km long and 450m thick. The ore deposits consists of complex-metal zoned volcanogenic massive sulphides contained within the Myra Formation of the Sicker Group volcanic assemblage. The Myra Formation hosts a geologically diverse collection of orebodies, including massive and disseminated polymetallic sulphides, zoned pyritic massive sulphides and stringer massive sulphide zones.
Exploration in the Marshall zone encountered high-grade polymetallic sulphides. Preliminary underground test development started in 1999 and underground drilling revealed 23m of massive sulphides grading 11.3% zinc, 1.4% copper, 3.6g/t gold and 264.3g/t silver.
Having started as an open pit in 1966, Myra Falls has more recently relied on underground bulk-mining methods. Having carried out an extensive programme of ground support in 19989, Boliden increased drift-and-fill mining to maximise reserve extraction.
Both current mines produce polymetallic ore and are serviced from a single production shaft at the 700m level. The two operations are linked by a 1.8km-long adit. The main production method in the H-W mine is sub-level stoping with longhole drilling, while sub-level stoping and drift-and-fill are used at Battle-Gap. Mined ore is hauled to an underground crusher and hoisted crushed ore is taken to the mill about 1km from the shaft.
Myra Falls uses conventional flotation technology to recover sulphide concentrates. The current mill was commissioned in 1985 and has been progressively modernised since then. In 1990, the copper and zinc flotation circuit was streamlined by adding column flotation cells and reducing the recirculation load to improve zinc recovery. In 1992, a Knelson gravity concentrator was added to each grinding circuit to improve gold recovery.
In 2005, Myra Falls produced 912,565t of ore grading 6.1% zinc, 1.2% copper, 51g/t silver and 1.8g/t gold. Its concentrate output contained 48,084t of zinc, 7,640t of copper, 31,750oz of gold and 1.17Moz of silver, giving a cash production cost of US$0.47/lb of zinc.
Lead is one of the earliest metals which were extracted from lead-zinc ore by humans. It is one of the soft metal, with blue-gray, hardness 1.5, specific gravity of 11.34, melting point 327.4 , boiling point 1750 , good ductility, which is can be easy made of alloy with other metals such as zinc, tin, antimony , arsenic, etc. Zinc is the last one in the ancient seven kinds of non-ferrous metals (copper, tin, lead, gold, silver, mercury, zinc). With blue-white, hardness 2.0, melting point 419.5 , boiling point 911 , when heated to 100 ~ 150 , it can have good pressure resistance, specific gravity 7.19 after rolling. Zinc can be made of alloy with a variety of non-ferrous or zinc alloy, the most important thing is that zinc and copper, tin, lead, brass composition, etc., can also be composed of aluminum, magnesium, copper die-casting alloys.
Zinc is an important non-ferrous material, its consumption is second only to copper and aluminum, zinc metal has good rolling resistance, wear resistance and corrosion resistance, with a variety of metals can be made of more excellent physical and chemical properties alloys. The main products can include zinc metal, zinc alloy, zinc oxide, these products have wide application. It can beused as anti-corrosion coating (such as galvanized sheet), widely used in automotive, construction, shipbuilding, light industry, the amount of zinc accounting for about 46%. It also can be used in automobile manufacturing and mechanical industries, the amount of zinc accounting for about 15%. It also has perfect performance in automobiles and light industry, the amount of zinc accounting for about 15%. In addition, the phenomenon of spark collision would not occur between zinc and other metals, so it is suitable for underground explosion-proof equipment. Zinc also can be used in pharmaceutical industry. Lead also has wide application which mainly used in Lead-acid batteries, chemicals, stereotype lead pipes, solder and lead bullets field.
Lead and zinc can be widely used in galvanizing, alloys, miscellaneous and so on.In fact, it almost can be used in all kinds of industries. With the rapid development of economy, more and more technical application would like to use lead and zinc, so it has wide and bright market. In the word, many customers would like to purchase lead and zinc mining equipment from China, because China mining equipment is high efficiency and low cost which can give them more profit that they wanted.
In the lead and zinc processing plant, it can be divided into many stages which mainly include crushing stage, grinding stage and beneficiation stage. Typically, lead and zinc ore crushing machine often used in the crushing process of lead-zinc bearing rocks. The lead and zinc grinding plant can use the ball mills, rod mills, and vertical mills. It also includeslead and zinc extraction equipment and lead and zinc refining equipment.

Maximise your savings and enjoy the peace of mind that comes with solar's top durability, reliability and efficiency,1Based on datasheet review of websites of top 20 manufacturers per IHS, as of January 2020. all backed by the industry's leading warranty.2Based on October 2019 review of warranties on manufacturer websites for top 20 manufacturers per IHS 2019.
SunPower Maxeonsolar panels are designed to be different, and proven to be betteracross more than five cell generations, 3.5 billion cells and 30 million panels, even in the harshest of conditions. Conventional solar cells lose power over time because of corrosion and breakage. The unique design of SunPower Maxeonsolar cells eliminates 86% of the reasons that conventional cells fail1Wohlgemuth, J. Reliability of PV Systems. Proceedings of SPIE, 2008. So your SunPower panels - and savings - continue to deliver. Year, after year, after year.
As the most efficient solar panel in the industry for more than 10 years1Based on datasheet review of websites of top 20 manufacturers per IHS, as of Jan, 2020. , SunPower Maxeon panels generate more power from the same roof than conventional panels, delivering up to 35% more energy from the same space over the first 25 years.2SunPower 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m)
Invest with confidence, knowing that SunPower Maxeon panel quality is proven. In actual field testing across 8 years and 800,000 panels at 264 sites, SunPower Maxeon solar panels demonstrated the lowest degradation rates in the industry,1Jordan, et al, Robust PV Degradation Methodology Application PVSC 2018 and Compendium of Photovoltaic Degradation Rates PiP 2016.almost 4x stronger reliability than conventional panels. In addition, each panel is backed by the industry-leading SunPower Complete Confidence Panel Warranty.2Based on October 2019 review of warranties on manufacturer websites for top 20 manufacturers per IHS 2018.
SunPower Maxeon panels were recognized as a Top Performer in the 2021 PVEL PV Module Reliability Scorecard. Based on data from its Product Qualification Program (PQP), the PVEL Scorecard highlights the exemplary reliability performance of solar panel manufacturers worldwide.
The patented metal foundation of SunPower Maxeon cells allows them to bend under tough conditions where others break. And SunPower Maxeon panels are proven, with an expected useful life of 40 years1SunPower Module 40-Year Useful Life," SunPower white paper. 2013. and a return rate of less than 0.005% on over 15 million panels shipped and studied2A Comparative Study: SunPower DC Solar Module Warranty Claim Rate vs. Conventional Panels." SunPower Corporation. 2019..
All SunPower residential and commercial panels are backed by the industry-leading 25-year coverage of the SunPower Complete Confidence panel warranty1The Complete Confidence Panel Warranty is a Maxeon Solar Technologies warranty available for its SunPower panels sold by SunPower distributors or sold and installed by SunPower authorised installation partners. For more information about the warranty terms and conditions available in your country, visit maxeon.com/legal. . Each panel is manufactured with the absolute confidence to deliver more energy, reliability and savings over timeand reinforced by extensive third-party testing and field data from more than 35 million panels deployed worldwide to ensure you get the best warranty available and complete peace of mind.
SunPower Maxeon panels provide greater peace of mind than Conventional Solar Panels1Conventional Panel is a panel made with Conventional Cells. Conventional Cells are silicon cells that have many thin metal lines on the front and interconnect ribbons soldered along the front and back..
SunPower Maxeon panels lead the solar industry in panel efficiency and deliver more bill savings by generating the most solar power and long-term solar energy in a given amount of roof space. That means they generate more power in the same space than all other panels on the market. In fact, the SunPower Maxeon 3 panel was the first 400 watt solar panel in European and Australian home solar, where most Conventional Panels are rated for 280 310 watts.
Over time, the advantage grows, because SunPower Maxeon panels also have the lowest degradation rate in the solar industry. While most Conventional Panels tend to degrade around 0.75%/year, SunPower Maxeon panels have proven to degrade at less than one-third of that rate, or about 0.2%/year2Jordan, et al, Robust PV Degradation Methodology Application PVSC 2018 and Compendium of Photovoltaic Degradation Rates PiP 2016.. To translate into real results that means a SunPower Maxeon panel delivers up to 25% more energy in its first year of operation. In year 25, that advantage grows to about 45% more energy, for an average of 35% more energy during the first 25 years3SunPower 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m).
SunPower Maxeon panels also deliver greater peace of mind, having earned the trust of experts by being more reliable and durableand backed by our industry-leading Complete Confidence Warranty. Not only is this warranty stronger, but unlike most conventional warranties, it is based on actual field-testing data. For example, the power warranty promises no more than a 0.25%/ year power drop the strongest power warranty in solar4Based on Oct. 2019 review of warranties on manufacturer websites for top 20 manufacturers per IHS 2018. This is backed by a study of more than 230MW across 149 actual global sites using a methodology developed in collaboration with NREL. We also know from actual field data that only 0.005% or 1 in 20,000 SunPower Maxeon panels have been returned under warranty5"A Comparative Study: SunPower DC Solar Module Warranty Claim Rate vs. Conventional Panels." SunPower Corporation. 2019.Lastly, SunPower Maxeon panels are built with our customers in mind, which means higher sustainability standards and more elegant design aesthetics than Conventional Panels. SunPower Maxeon panels have pioneered sustainability efforts in solar manufacturing, and have been recognized with the prestigious Cradle to Cradle Certified designation for direct current (DC) panels. The Cradle to Cradle designation demonstrates the products' quality based on rankings of material health, material reutilization, renewable energy use, water stewardship, and social fairness.
SunPower Maxeon panels were also the first and only solar panel to disclose its ingredients through the Declare label available for all Maxeon 2 and 3 panels. In March 2020, our Mexicali, Mexico manufacturing facility was re-certified by NSF Sustainability as Zero Waste to Landfill and remains the only solar panel manufacturing facility to achieve this. The certification means that this facility diverts more than 99% of its waste, with 1% or less going to landfills.
The back-contact cell design of SunPower Maxeon panels also delivers an uncluttered and elegant design aesthetic with panels available in black and white backsheets. This has made SunPower Maxeon panels the panel of choice for architects and designers.
SunPower Performance solar panels utilize high efficiency mono PERC cells to deliver higher reliability and efficiency than Conventional Cells. For more information on Performance Panels, visit the Performance panels page.
The SunPower Maxeon panel advantage begins with its cell. The SunPower Maxeon cell is a fundamentally different design from any other cell on the market, starting with a solid copper foundation that is unique in the solar industry.
In contrast, what appears to be metal on the front and back of a Conventional Cell is actually conductive paste made of tiny bits of silver and aluminum baked onto the silicon wafer. In fact, the process of making those cells is very similar to screen-printing a design on a tee-shirt: you create a template, wipe the paint across the template and then remove the template to leave the paint where you want it on the tee-shirt, and then bake the tee-shirt to cure the paint onto the fabric. A similar screen-printing process is used to apply the thin lines of metal paste on the front, and the full-coverage metal paste on the back, to create a Conventional Solar Cell. Unlike the strength of the solid copper foundation of the SunPower Maxeon cell, the metal paste of the Conventional Cell offers almost no strength to the thin silicon wafer. This fundamental design difference creates the weakness you can find through basic laboratory testing.
A SunPower Maxeon solar panel delivers up to 25% more energy than a Conventional Panel in its first year of operation. In year 25, the difference would grow to about 45% more energy, for an average of 35% more energy during the first 25 years1SunPower 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m) 2 SunPower Module 40-year Useful Life. SunPower whitepaper. 2013. SunPower Maxeon solar panels are predicted to have a useful life of more than 40 years2SunPower Module 40-year Useful Life. SunPower whitepaper. 2013.
With solar, as with many things, you get what you pay for. Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for Conventional Panels that might cost less out-of-pocket, you can expect to see average (or below average) results and less savings over time.
A higher quality panel like SunPower Maxeon might cost a little more up front, but you will see more predictable performance in the long run. SunPower Maxeon panels generate more energy, last longer, are backed by a stronger warranty, and are produced more sustainably than Conventional Panels. This means SunPower Maxeon panels will offset more of your electricity bill, saving you more, and do so with the peace of mind you expect from a top-quality product.
Solar desalination is one of the mostsustainable solutions to produce freshwater from brackish water. The present research work aims to experimentally investigate the effect of a V-shape concentrator integrated with solar still (SS). The V-shape concentrator integrated with the conventional solar still (CSS) is used to supply the saline water at elevated temperature to the basin of SS, which augments the freshwater yield compared to CSS. The experimental investigation was performed at different brackish water depths of 0.01, 0.02, and 0.03 m, respectively. The SS system was evaluated based on water yield, energy, exergy, concentrator efficiency, and economicanalysis. The freshwater yield of the solar still integratedwith V-shape concentrator (SSVC) was found to be 5.47, 5.10, and 4.89 L/m2.day, whereas the yield of the CSS was 3.73, 3.27, and 2.91 L/m2 .day at thewater depths of 0.01, 0.02, and 0.03 m, respectively. The daily energy and exergy efficiency of CSS were 38.5, 33.5, and 29.4% and 1.9, 1.5, and 0.97 % in the case of 0.01, 0.02, and 0.03m water depth , respectively. However, the integration of concentrator significantly augmented the energy efficiency to 57.4, 51.7, and 44.9% and exergy efficiency to 3.8, 3.3, and 2.8% for the respective water depths . Life cycle studies demonstrated that the freshwatercost per liter for CSS and SSVC were 0.0102 $ and 0.0117 $ respectively, at a water depth of 0.01 m. It was concluded that the addition of V-shape concentrator and minimum water depth is useful to augment the energy efficiency, exergy efficiency, and yield of the SS in the very economical way.

Norilsk is in Krasnoyarsk Krai, Russia, and located above the Arctic Circle. Since there are no roadway or railway connections, all freight is delivered by cargo ship via the Arctic Ocean to the Port of Dudinka, in Murmansk, or by air. The Robit drilling consumables are to be delivered by sea, Robit said.
Norilsk Nickel is one of Russias leading metals and mining company, a manufacturer of palladium and refined nickel, and one of the biggest platinum and copper producers in the world. The company also produces cobalt, rhodium, silver, gold, iridium, ruthenium, selenium, tellurium, and sulphur.
Robit, meanwhile, provides drilling consumables for applications in mining, construction and contracting, tunnelling, and well drilling. It has two product and service ranges: top hammer and down-the-hole.
Last month, the company signed a two-year contract to supply drilling tools to Al Masane Al Kobra Mining Co, in Saudi Arabia, for underground jumbo rigs at its Al Masane copper-zinc mine. The tools are to be supplied by Robits distributor, Bin Harkhil.
Outotec President and CEO, Markku Tersvasara, says the company saw signs of increased greenfield investments in both minerals processing and metal refining technologies in the most recent March quarter, providing the company with a positive outlook for the rest of 2019.
The mineral processing and refining company reported 1% year-on-year growth, to 336.1 million ($370.7 million) in the first three months of 2019, alongside a 22% boost in service order intake (159.9 million) and adjusted EBIT of 11 million, up from 7 million a year earlier.
While overall sales dipped 11% year-on-year to 254.7 million and the company reported negative net cash from operating activities, Tersvasara painted an upbeat picture in his statement accompanying these results.
The overall market sentiment developed positively in the first quarter, he said. In addition to brownfield investments, we are seeing signs of increased greenfield investments in both minerals processing and metal refining technologies. Order intake was at the same good level as in the first quarter last year. I am pleased with the 22% growth in service orders and the 19% increase in equipment orders for Minerals Processing.
He said sales decreased primarily due to fewer plant and equipment deliveries, but there was a clear improvement in profitability, both in absolute and relative terms, due to better gross margins (27.1% in Q1 2019, up from 22.8% in Q1 2018).
Tersvasara added: I am pleased with the progress in our must-win battles that further improve our performance. These programs focus on strengthening customer focus, service business, product competitiveness, project competencies and people development.
He also commented on the ilmenite smelter project that has hit the companys recent financial results, saying negotiations were ongoing in cooperation with the customer and that the company remained confident we are provided adequately for the project.
The Saudi Arabian Mining Company (Maaden) has awarded the consortium of Outotec and Larsen & Toubro with an engineering, procurement and construction contract to build a greenfield mineral concentrator and gold processing plant in the Kingdom of Saudi Arabia, the Finland-based company says.
The order, worth some 140 million ($157 million) to Outotec, is almost evenly shared between the reporting segments and will be booked into Outotecs June quarter 2019 order intake, the company said. The total value of the project is around 540 million.
Outotecs delivery includes basic and detail engineering, procurement and delivery of process equipment, commissioning, start-up assistance and training services. The new gold processing plant is due to be completed in 2022, it said.
Maaden is a leader of the Saudi Arabia mining industry, and an internationally recognised mining company with a global presence, thanks to partnerships with the likes of Barrick Gold, Alcoa and the Mosaic Company.
The Mansourah & Massarah operation will be built in the Central Arabian gold region, with the processing plant capable of up to 4 Mt/y throughput. The concentrator and the gold processing plant has been designed to produce an average of 250,000 oz/y of gold per year over the life of mine, Outotec said.
Our previous deliveries have included grinding, flotation and filtering technologies as well as alumina calcination technology, and three sulphuric acid plants. Our proven technologies and services enable them to get the best value from their resources and build sustainable operations.
X-ray ore sorting is already making great waves across the mineral processing industry by reducing plant throughputs, increasing head grades and cutting operating costs. One of the leaders in this growing field, TOMRA, believes its newCOM XRT 2.0 sorter takes these attributes to another level.
This upgraded model features higher belt speed and throughput, translating directly into increased productivity in mineral processing. It also offers increased wear resistance and longer component lifetime, with quick and safe maintenance through providing easier access to replaceable components.
Ines Hartwig, Product Manager at TOMRA Sorting Mining, said the valuable experience gained over the past 15 years, through monitoring and maintaining the TOMRA COM XRT units operating in the field, has been incorporated into the design of the TOMRA COM XRT 2.0.
The speed of the belt in the new design has been increased from 2.7 m/s to 3.5 m/s, while the more powerful X-ray system accommodates the sorting of larger-sized material due to better X ray penetration.
Higher levels of belt occupancy are facilitated by our improved data processing capacity, and this allows the particle size of the feed to be increased, she said. The maximum size of the particles that the TOMRA COM XRT 2.0 can handle is between 100 mm and 125 mm, depending on the material, which also contributes significantly to throughput capacity.
The unit boasts a highly selective ejection system, using data processing in combination with precise control of the pneumatic valves which eject the selected material from the stream. Driving this system is TOMRAs proprietary data processing pipeline that links sensors, image processing and the valve control boards.
The performance of this ore sorting technology has been proven at Maaden Phosphates new $560 million processing plant at the Umm WuAl project in Saudi Arabia, one of the largest integrated phosphate fertiliser facilities in the world, according to TOMRA. TOMRA Sorting Solutions has installed nine of its TOMRA COM XRT sorting units, each with an operational width of 2.4 m, to process a 1,850 t/h sorter feed at this facility (pictured, top).
The objective of the sorters is to reduce the milling and flotation of silica in the plant process, using a dry technology at a low cost per tonne. The TOMRA units achieve this by removing more than 90% of the chert in the +9 mm fraction, which makes up half of the plant feed, before the phosphate is fed to the milling and flotation circuit. This leads to the removal of over 1.2 Mt/y of SiO2, which does not have to be crushed, ground and floated.
This installation considerably improved the mill performance by reducing the consumption of energy, water and chemicals per tonne of final product, TOMRA said. All of this was achieved with a smaller sorting plant footprint. The saving in flotation reagents, alone, amounts to almost $8 million/y, according to the company.
In Botswana, TOMRA Sorting Solutions has installed two TOMRA COM XRT 2.0/1200 sorters in the mega-diamond recovery (MDR) circuit of Lucara Diamonds Karowe mine. Located directly after the primary crusher and ahead of the process plant, the MDR circuit treats material in the size range between 50 mm and 120 mm. It maximises the upfront recovery of exceptional diamonds before the ore reaches the comminution processes, where diamond damage may occur.
TOMRA Sorting Solutions also has several smaller units in portable and containerised configurations in many different countries, where they must operate in a variety of climatic conditions from arctic to tropical. These machines sort minerals ranging from copper, iron ore and coal to industrial minerals, chrome and diamonds.
The Saudi Arabian Mining Company (Maaden) and GE have signed a strategic memorandum of understanding that could see digital solutions installed across the mining companys gold, copper, aluminium, and phosphate operations.
Maaden has been pursuing a number of partnerships to capture the opportunities found in digitisation and innovation, and will invest in the application of pioneering technologies in its operations in Saudi Arabia in order to remain ahead of the competition and reinforce the company as a global mining leader, the company said.
GEs digital mining solutions will look at specific areas of Maadens operations to improve ore grades, reduce fuel and energy costs and usage, improve equipment reliability and availability, cut maintenance costs, and boost productivity and efficiency across operations.
GE Minings Digital Mine is made up of technologies to help improve performance, reliability, and operations while promoting safer mining practices through intelligent, real-time monitoring across the mine.
Powered by GEs Predix platform, the only Industrial Internet platform built exclusively for industry, Digital Mine enables operators to make data-driven decisions that improve equipment reliability and optimise mine operations, GE says.
Darren Davis (picture, left, signing the agreement), Maaden Acting President and CEO, said of the GE partnership: The Kingdom of Saudi Arabia has high aspirations for the deployment of new technology and the digitisation of industrial landscape in the country. Maaden is committed to championing the responsible development of the mining sector as a major pillar of the Saudi economy and digitalisation, as part of the fourth industrial revolution, will be key to ensuring we achieve our goal of becoming a sustainable mining champion.
Bill Ruh (pictured, right), President and CEO, GE Digital, said: The scale and impact of organisations such as Maaden is enormous, and we know that the optimisation and increases in efficiency will have a major impact on the company and the country.
Earlier this year, GE and South32 signed a three-year strategic partnership to help develop the mining companys technology roadmap and digital transformation programme. GE is also working with Rio Tinto to optimise its Pilbara rail operations and Vedanta in South Africa on its Gamsberg digitisation programme.Get in Touch with Mechanic
