Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation, and they satisfied mankind's needs for nearly 3,000 years. By the end of the Industrial Revolution, however, most of these direct-smelting ores had been consumed. Concentration was now necessary, but the means for achieving it were limited to simple mechanical schemes such as sluicing and screening or the most basic method of all, hand sorting. In the late nineteenth and early twentieth centuries, the demand for metals overwhelmed such capabilities, and an array of new beneficiation techniques appeared: jigs, tables, spirals, and a truly revolutionary process called froth flotation.

Many other methods have been used for minerals beneficiation. Electrostatic separation utilizes the difference in electrical conductivity between the mineral and the gangue. Air tabling relies upon particle density and shape for separation. Other methods exploit characteristics such as color, radioactivity, and heat capacity. The selection and application of the appropriate beneficiation methods are vital to the economic success of every mineral processing venture. Hazen's expertise includes the full range of mineral processing technologies, and our experienced metallurgical staff can provide accurate, timely, and cost-effective solutions to your mineral processing and beneficiation problems.

mbe minerals outlines coal beneficiation capability - international mining

mbe minerals outlines coal beneficiation capability - international mining

The coal beneficiation sector depends on robust products that provide ease of operation, minimised maintenance costs and enhanced productivity, states MBE Minerals, the major supplier of coal beneficiation technology, whose range covers basic and detailed engineering to components for complete plants and systems. This includes modernisation and upgrades, in addition to capacity increase measures and automation and process control equipment. The company adds that each application is assessed carefully in conjunction with the customer in a comprehensive site visit to determine the equipment that will provide the optimal solution. An extensive local and international footprint allows MBE Minerals to leverage the experience and expertise necessary to ensure a profitable and sustainable end result. Its full scope of services includes feasibility studies, raw material testing, financing concepts, erection and commissioning, personnel training and pre- and after-sales service.

The PNEUFLOT pneumatic flotation system was introduced into the market in 1987, with the first coal flotation installation at Pittston Pennsylvania in the US. Since then the technology has been used widely for fine coal slurry treatment. By 2013, 82 PNEUFLOT units had been installed in 12 countries, treating some 35,930 m/h or 3,228 t/h of fine coal slurries. Currently PNEUFLOTs largest installation base is China and India, with the technology expanding rapidly into Eastern Europe and other parts of Asia. Test work has proved that PNEUFLOT can produce a Waterberg flotation concentrate with less than 11% ash at yields greater than 33% and organic efficiencies greater than 68%. In 2012 MBE Minerals took the decision to introduce PNEUFLOT into the Sub-Saharan market. To address the key concern that the technology remained untested on South African coals, MBE Minerals invested in a laboratory cell and pilot plant. These units have been used to test material from both the Soutpansberg and the Central Basin over the past year. The laboratory cell has achieved product with less than 10% ash (feed +50% ash) for a Soutpansberg seam while the pilot plant produced a bulk product sample from the tails of a Central Basin plant fit for market acceptance presentation by a coal major.

Prior to the design of an industrial scale flotation plant, laboratory scale test work and where possible semi-industrial pilot test work has to be carried out. The pilot plant can be installed anywhere in an existing circuit as a plug and play device and the results generated can be scaled up directly to a full scale application. MBE Minerals offers a full testing programme in Southern Africa. The laboratory cell is equipped with a 50 litre conditioning agitator tank, where feed rates of 300 to 400 litres per hour can be applied. The pilot plant works with an agitated feed/conditioning tank with a volume of 1 m for batch operations and can accommodate feed rates of up to 10 m/h for continuous in-plant trials. Industrial machine sizes from 0.8 m to 6 m diameter are available. Slurry feed rates from 10 to 1,400 m/h (4 to 560 t/h dry solids) can be processed in one cell depending on the cell diameter. The number of required cells and stages is calculated from the test results. MBE Minerals designs the flotation process flow sheet accordingly and can provide customers with a 10% cost estimate and process guarantees based on both laboratory and pilot/semi industrial scale test work. PNEUFLOT technology works effectively at lower operating costs through much lower energy and maintenance and repair costs compared to column or mechanical agitator flotation. Advantages such as no moving parts, low wear and atmospheric aeration, negating the need for a blower or compressor adds value to a user friendly system, together with low maintenance, low costs and low down time.

The turbulence in the PNEUFLOT cell is comparatively low and the wide bubble size range in the self aspirated aerator can be varied by changing the speed of the feed slurry rate and using a frequency converter on the motor power supply. PNEUFLOT copes well with material sizes of 80% passing from 45, 180, 350, 500 or 1,000 microns in the same machine design (size) thus de-risking variations in feed conditions. This also allows the equipment to be used for all flotation stages, from rougher, scavenger and cleaner through to re-cleaner stages. Gregory Niekerk, Business Development Manager, MBE Minerals South Africa, says: Users have recognised better selectivity compared to conventional agitator flotation systems, higher recoveries in fewer stages compared to column flotation and lower wear and reduced energy consumption, with a smaller plant footprint, as definitive reasons for selecting PNEUFLOT over conventional technologies for the flotation of fine coal slurries.

MBE Minerals says its BATAC jig technology has undergone extensive test work to prove its capability to deliver increased efficiencies, improved product quality and higher availability and throughput rates. It represents the latest advances in stratification by means of jigging, one of the oldest separation methods deployed in coal and mineral beneficiation. BATAC jig technology has developed a reputation for its excellent separation accuracy, combined with a fairly small footprint, which translates into a lower capital cost. This remarkable accuracy is due to electronic control of the air pulse generator and sensing of the thickness and densities of the material layers being separated. MBE Minerals introduced BATAC jig technology to the market in the 1960s specifically to overcome the counter-productive limitations of traditional technology. The under-bed pulsated BATAC jig is ideal for coarse applications from 150 mm down to fine coal in the 10 to 0.5 mm size range, with throughput rates of between 100 and 1,200 t/h.

The ROMJIG has proved particularly suitable as a reliable and economical solution in destoning raw coal. Extensive international testing has produced impressive results, with an operational efficiency (imperfection) of I=0.08 to 0.1. There was also an overall reduction in the stone handled and indications of a lower percentage of refuse in the washery feed, says MBE Minerals Managing Director, Johannes Kottmann. This translates into cost-saving benefits such as reduced wear on machinery and transporting equipment, less grain degradation, less dust and slurry and reduced consumption of flocculation and flotation agents in downstream fines recovery circuits.

MBE Minerals says it has also built up a formidable reference base of vibrating screens in the African mining industry, having supplied products to the coal, diamond and iron ore sectors for the past 40 years for applications from sizing to scalping, dewatering and media recovery. These vibrating screens therefore have a proven track record under arduous and demanding conditions. They are available in a variety of sizes of up to 3.6 m in width and 6.75 m in length, in single or double deck configuration and in either circular or linear motion. Particular innovations introduced by MBE Minerals include an innovative side plate mounted drive, which means they are much more lightweight than those using vibrator motors. However, screens can be supplied with vibrator motors if necessary, while resonance screens offer the added benefit of lower power consumption. All types of screening surfaces can be accommodated, with each screen incorporating mechanical design features such as vibration dampening, side plates, cross members and the appropriate feed and discharge chutes.

Finally, the TESKA dense media separator is a slowly revolving bucket wheel joined to the separating compartment by seals. The bucketwheel for sinks has been partitioned into compartments by means of perforated plates that enable removal of the sinks, while the floats run towards a discharge paddle wheel. A very precise cut point is therefore possible due to this higher stability, controllable by a two-way medium flow of the separation bath. Dense media separation occurs in a suspension of finely ground solids and water. In this kind of media, particles of high specific gravity settle at the bottom, while particles of lower specific gravity, such as coal, tend to float. The TESKA dense media separator is used for coal of +6 mm size, with capacities of up to 800 t/h. A special feature is the large bath width relative to the size of the machine. It can be supplied with bucket wheel diameters of up to 6,500 mm, bucket widths of up to 1,500 mm and bath widths of up to 3,000 mm. Feed sizes of up to 1,200 mm edge length can be processed. If magnetite is used as the heavy medium, then the TESKA dense media separator will accommodate medium densities of up to 2.3 g/cm.

economic advantages of dry triboelectric separation of minerals - st equipment & technology (stet)

economic advantages of dry triboelectric separation of minerals - st equipment & technology (stet)

The enhanced separation capabilities of the STET system may be a very effective alternative to flotation processes. An economic comparison conducted by an independent mineral processing consulting firm of the triboelectrostatic belt separator versus conventional flotation for barite/quartz separation illustrates the advantages of dry processing for minerals. Utilizing this dry process results in a simpler process flow sheet with less equipment than flotation with both capital and operating expenses reduced by 30%.

The ST Equipment & Technology LLC (STET) triboelectrostatic belt separator provides the mineral processing industry a means to beneficiate fine materials with an entirely dry technology. The high efficiency multi-stage separation through internal charging/recharging and recycle results in far superior separations than can be achieved with other conventional single-stage electrostatic systems. The triboelectric belt separator technology has been used to separate a wide range of materials including mixtures of glassy aluminosilicates/carbon, calcite/quartz, talc/magnesite, and barite/quartz. The enhanced separation capabilities of the STET system may be a very effective alternative to flotation processes. An economic comparison conducted by an independent mineral processing consulting firm of the triboelectrostatic belt separator versus conventional flotation for barite / quartz separation illustrates the advantages of dry processing for minerals. Utilizing this dry process results in a simpler process flow sheet with less equipment than flotation with both capital and operating expenses reduced by 30%.

The lack of access to fresh water is becoming a major factor affecting the feasibility of mining projects around the world. According to Hubert Fleming, former global director for Hatch Water, Of all the mining projects in the world that have either been stopped or slowed down over the past year, it has been, in almost 100% of the cases, a result of water, either directly or indirectly (Blin 2013)1. Dry mineral processing methods offer a solution to this looming problem.

Wet separation methods such as froth flotation require the addition of chemical reagents that must be handled safely and disposed of in an environmentally responsible manner. Inevitably it is not possible to operate with 100% water recycle, requiring disposal of at least of portion of the process water, likely containing trace amounts of chemical reagents.

Dry methods such as electrostatic separation will eliminate the need for fresh water, and offer the potential to reduce costs. One of the most promising new developments in dry mineral separations is the triboelectrostatic belt separator. This technology has extended the particle size range to finer particles than conventional electrostatic separation technologies, into the range where only flotation has been successful in the past.

The triboelectrostatic belt separator utilizes electrical charge differences between materials produced by surface contact or triboelectric charging. When two materials are in contact, material with a higher affinity for electrons gains electrons and thus charges negative, while material with lower electron affinity charges positive. This contact exchange of charge is universally observed for all materials, at times causing electrostatic nuisances that are a problem in some industries. Electron affinity is dependent on the chemical composition of the particle surface and will result in substantial differential charging of materials in a mixture of discrete particles of different composition.

In the triboelectrostatic belt separator (Figures 1 and 2), material is fed into the thin gap 0.9 1.5 cm (0.35 -0.6 in.) between two parallel planar electrodes. The particles are triboelectrically charged by interparticle contact.

For example, in the case of coal combustion fly ash, a mixture of carbon particles and mineral particles, the positively charged carbon and the negatively charged mineral are attracted to opposite electrodes. The particles are then swept up by a continuous moving open-mesh belt and conveyed in opposite directions. The belt moves the particles adjacent to each electrode toward opposite ends of the separator. The electric field need only move the particles a tiny fraction of a centimeter to move a particle from a left-moving to a right-moving stream. The counter current flow of the separating particles and continual triboelectric charging by carbon-mineral collisions provides for a multistage separation and results in excellent purity and recovery in a single-pass unit. The high belt speed also enables very high throughputs, up to 40 tons per hour on a single separator. By controlling various process parameters, such as belt speed, feed point, electrode gap and feed rate, the device produces low carbon fly ash at carbon contents of 2 % 0.5% from feed fly ashes ranging in carbon from 4% to over 30%.

The separator design is relatively simple. The belt and associated rollers are the only moving parts. The electrodes are stationary and composed of an appropriately durable material. The belt is made of plastic material. The separator electrode length is approximately 6 meters (20 ft.) and the width 1.25 meters (4 ft.) for full size commercial units. The power consumption is about 1 kilowatt-hour per ton of material processed with most of the power consumed by two motors driving the belt.

The process is entirely dry, requires no additional materials and produces no waste water or air emissions. In the case of carbon from fly ash separations, the recovered materials consist of fly ash reduced in carbon content to levels suitable for use as a pozzolanic admixture in concrete, and a high carbon fraction which can be burned at the electricity generating plant. Utilization of both product streams provides a 100% solution to fly ash disposal problems.

The triboelectrostatic belt separator is relatively compact. A machine designed to process 40 tons per hour is approximately 9.1 meters (30 ft) long, 1.7 meters (5.5 ft.) wide and 3.2 meters (10.5 ft.) high. The required balance of plant consists of systems to convey dry material to and from the separator. The compactness of the system allows for flexibility in installation designs.

The triboelectrostatic belt separation technology greatly expands the range of materials that can be beneficiated by electrostatic processes. The most commonly used electrostatic processes rely on differences in the electrical conductivity of the materials to be separated. In these processes, the material must contact a grounded drum or plate typically after the material particles are negatively charged by an ionizing corona discharge. Conductive materials will lose their charge quickly and be thrown from the drum. The non-conductive material continues to be attracted to the drum since the charge will dissipate more slowly and will fall or be brushed from the drum after separation from the conducting material. These processes are limited in capacity due to the required contact of every particle to the drum or plate. The effectiveness of these contact charging processes are also limited to particles of about 100 m or greater in size due to both the need to contact the grounded plate and the required particle flow dynamics. Particles of different sizes will also have different flow dynamics due to inertial effects and will result in degraded separation. The following diagram (Figure 4) illustrates the fundamental features of this type of separator.

Triboelectrostatic separations are not limited to separation of conductive / non-conductive materials but depend on the well known phenomenon of charge transfer by frictional contact of materials with dissimilar surface chemistry. This phenomenon has been used in free fall separation processes for decades. Such a process is

illustrated in Figure 5. Components of a mixture of particles first develop different charges by contact either with a metal surface, or by particle to particle contact in a fluidized bed feeding device. As the particles fall through the electric field in the electrode zone, each particles trajectory is deflected toward the electrode of opposite charge. After a certain distance, collection bins are employed to separate the streams. Typical installations require multiple separator stages with recycle of a middling fraction. Some devices use a steady stream of gas to assist the conveying of the particles through the electrode zone.

This type of free fall separator also has limitations in the particle size of the material that can be processed. The flow within the electrode zone must be controlled to minimize turbulence to avoid smearing of the separation. The trajectory of fine particles are more effected by turbulence since the aerodynamic drag forces on fine particles are much larger than the gravitational and electrostatic forces. The very fine particles will also tend to collect on the electrode surfaces and must be removed by some method. Particles of less than 75 m cannot be effectively separated.

Another limitation is that the particle loading within the electrode zone must be low to prevent space charge effects, which limit the processing rate. Passing material through the electrode zone inherently results in a single-stage separation, since there is no possibility for re-charging of particles. Therefore, multi-stage systems are required for improving the degree of separation including re-charging of the material by subsequent contact with a charging device. The resulting equipment volume and complexity increases accordingly.

In contrast to the other available electrostatic separation processes, the triboelectrostatic belt separator is ideally suited for separation of very fine (<1 m) to moderately coarse (300m) materials with very high throughputs. The triboelectric particle charging is effective for a wide range of materials and only requires particle particle contact. The small gap, high electric field, counter current flow, vigorous particle-particle agitation and self-cleaning action of the belt on the electrodes are the critical features of the separator. The high efficiency multi-stage separation through charging / recharging and internal recycle results in far superior separations and is effective on fine materials that cannot be separated at all by the conventional techniques.

The triboelectrostatic belt separation technology was first applied industrially to the processing of coal combustion fly ash in 1995. For the fly ash application, the technology has been effective in separating carbon particles from the incomplete combustion of coal, from the glassy aluminosilicate mineral particles in the fly ash. The technology has been instrumental in enabling recycle of the mineral-rich fly ash as a cement replacement in concrete production. Since 1995, 19 triboelectrostatic belt separators have been operating in the USA, Canada, UK, and Poland, processing over 1,000,000 tons of fly ash annually. The technology is now also in Asia with the first separator installed in South Korea this year. The industrial history of fly ash separation is listed in Table 1.

Electrostatic separations have been extensively used for beneficiation for a large range of minerals Manouchehri-Part 1 (2000). While most application utilize differences in electrical conductivity of materials with the corona-drum type separators, triboelectric charging behavior with free-fall separators is also used at industrial scales Manouchehri-Part 2 (2000). A sample of applications of triboelectrostatic processing reported in the literature is listed in Table 2. While this is not an exhaustive listing of applications, this table illustrates the potential range of applications for electrostatic processing of minerals.

Extensive pilot plant and field testing of many challenging material separations in the minerals industry have been conducted using the triboelectrostatic belt separator. Examples of separation results are shown in Table 3.

Use of the triboelectrostatic belt separator has been demonstrated to effectively beneficiate many mineral mixtures. Since the separator can process materials with particle sizes from about 300 m to less than 1 m, and the triboelectrostatic separation is effective for both insulating and conductive materials, the technology greatly extends the range of applicable material over conventional electrostatic separators. Since the tribo- electrostatic process is entirely dry, use of it eliminates the need for material drying and liquid waste handling from flotation processes.

A comparative cost study was commissioned by STET and conducted by Soutex Inc. Soutex is a Quebec Canada based engineering company with extensive experience in both wet flotation and electrostatic separation process evaluation and design. The study compared the capital and operating costs of triboelectrostatic belt separation process to conventional froth flotation for the beneficiation of a low-grade barite ore. Both technologies upgrade the barite by removal of low density solids, mainly quartz, to produce an American Petroleum Institute (API) drilling grade barite with SG greater than 4.2 g/ml. Flotation results were based on pilot plant studies conducted by the Indian National Metallurgical Laboratory (NML 2004)18. Triboelectrostatic belt separation results were based on pilot plant studies using similar feed ores. The comparative economic study included flowsheet development, material and energy balances, major equipment sizing and quotation for both flotation and tribo- electrostatic belt separation processes. The basis for both flowsheets is the same, processing 200,000 t/y of barite feed with SG 3.78 to produce 148,000 t/y of drilling grade barite product with SG 4.21 g/ml. The flotation process estimate did not include any costs for process water, or water treatment.

Theses flowsheets do not include a raw ore crushing system, which is common to both technologies. Feed grinding for the flotation case is accomplished using a wet pulp ball mill with cyclone classifier. Feed grinding for the triboelectrostatic belt separation case is accomplished using a dry, vertical roller mill with integral dynamic classifier.

The triboelectrostatic belt separation flowsheet is simpler than flotation. Tribo-electostatic belt separation is achieved in a single stage without the addition of any chemical reagents, compared to three-stage flotation with oleic acid used as a collector for barite and sodium silicate as a depressant for the silica gangue. A flocculant is also added as a reagent for thickening in the barite flotation case. No dewatering and drying equipment is required for triboelectrostatic belt separation, compared to thickeners, filter presses, and rotary dryers required for the barite flotation process.

A detailed capital and operating cost estimate was performed by Soutex for both technologies using equipment quotations and the factored cost method. The operating costs were estimated to include operating labor, maintenance, energy (electrical and fuel), and consumables (e.g, chemical reagent costs for flotation). The input costs were based on typical values for a hypothetical plant located near Battle Mountain, Nevada USA.

The total cost of ownership over ten years was calculated from the capital and operating cost by assuming an 8% discount rate. The results of cost comparison are present as relative percentages in Table 4

The total purchase cost of capital equipment for the triboelectrostatic belt separation process is slightly less than for flotation. However when the total capital expenditure is calculated to include equipment installation, piping and electrical costs, and process building costs, the difference is large. The total capital cost for the tribo- electrostatic belt separation process is 63.2% of the cost of the flotation process. The significantly lower cost for the dry process results from the simpler flowsheet. The operating costs for the triboelectrostatic belt separation process is 75.5% of the flotation process due to mainly lower operating staff requirements and lower energy consumption.

The total cost of ownership of the triboelectrostatic belt separation process is significantly less than for flotation. The study author, Soutex Inc., concluded that the triboelectrostatic belt separation process offers obvious advantages in CAPEX, OPEX, and operational simplicity.

The triboelectrostatic belt separator provides the mineral processing industry a means to beneficiate fine materials with an entirely dry technology. The environmentally friendly process can eliminate wet processing and required drying of the final material. The process requires little, if any, pre-treatment of the material other than grinding and operates at high capacity up to 40 tons per hour by a compact machine. Energy consumption is low, less than 2 kWh/ton of material processed. Since the only potential emission of the process is dust, permitting is relatively easy.

A cost study comparing the triboelectrostatic belt separation process to conventional froth flotation for barite was completed by Soutex Inc. The study shows that the total capital cost for for the dry triboelectrostatic belt separation process is 63.2% of the flotation process. The total operating cost for triboelectrostatic belt separation is 75.8% of operating cost for flotation. The studys author concludes that the dry, triboelectrostatic belt separation process offers obvious advantages in CAPEX, OPEX, and operational simplicity.
