5 gold extraction methods to improve your recovery rate | fote machinery

The crushing and screening stage in the industry is mainly composed of three-stage and a closed-circuit process. Gold ores need to go through coarse, medium, and fine crushing processes to be minimized into smaller pieces. The screening equipment is used to sieving the smaller gold ores into the proper size for the next steps.

The grinding operation usually adopts one or two ball mills with types of lattice and overflow. The second stage grinding operation forms a closed circuit with a spiral classifier or a hydro cyclone to ensure the grinding fineness.

Since traditional ball milling equipment appears some shortcomings such as fast wear and large energy consumption, many manufacturers adopt new wear-resisting rubber lining boards, sliding bearing to improve a mill operation efficiency and prolong a machine's service life.

The beneficiation stage is a crucial part of gold extraction during the whole gold ore processing plant. Placer gold mine and rock gold mine are most widely processed to extract gold concentration.

The gold slurry process of the carbon slurry method (CIP and CIL) is to put activated carbon into cyanide ore slurry, adsorb dissolved gold on activated carbon, and finally to extract gold from activated carbon.

Equipment required for carbon slurry gold mining process: Leaching mixing tank, activated carbon screen, Two-layer (three-layer) washing and thickening machine, fast desorption electrolysis system with high-efficiency and low-consumption, high-frequency dewatering screen.

It means that by ion exchange resin, gold also can be extracted from ore pulp. Like carbon, the process makes gold absorbed onto solid spherical polystyrene resin beads instead of activated carbon grains.

According to different physical and chemical properties of different types of gold ores, flotation separation utilizes various reagents to make the gold attached to the bubbles then scraping these gold particles from blades to get the concentrate.

A jigger is one of the main pieces of equipment in the gravity separation process. The jigging process mixes gold ore particles of different specific gravity together, then stratifying these particles. The minerals with small specific gravity will be on the upper layer while the minerals with large specific gravity will be on the lower layer.

A shaking table is used to process gold ores in the horizontal medium flow. The motor drives the surface of the shaker to perform the longitudinal reciprocating motion, as well as the differential motion of the washing stream and the surface of the bed. Gold ore particles are stratified perpendicular to the surface of the bed, then being separated parallel to the surface of the bed in reciprocating motion which allows gold ores with different particle sizes to be discharged from different parts to achieve separation.

It adopts lope water flow to achieve separation. With the effect of the combined force of water flow, mineral gravity, the friction created by the bottom of the tank, and ore particles, the gold ore particles will settle in different areas of the tank. The ore particles with small specific gravity will flow away with the water, while ore particles with larger specific gravity would stay.

geology of native gold - jxsc machine

geology of native gold - jxsc machine

1. At 4.5 billion years ago, the Earth was formed as a large fireball with a high temperature enough to melt most minerals. Many small celestial bodies in the universe carry some metal elements (including gold). When the celestial body hits the earth, the meteorite is melted, and the gold remains. Because of the high density of gold, gold sinks into the earth, so now gold mining action is all underground.

2. According to scientists measurements and estimates, the Earths total gold reserves are about 4.8 billion tons, while about 4.7 billion tons are distributed in the core, and the mantle is 86 million tons, while the distribution to the earths crust is less than 100 million tons. More than 99% of the gold on the earth enters the core. This distribution of gold is formed during the long-term evolution of the Earth. The earths crust formed in the early stage of the earths development has a high abundance of gold. Therefore, it can represent the Archean greenstone belt composed of the early residual crust, especially the combination of mafic and ultramafic volcanic rocks, which may become the earliest gold deposits.

3. The gold treasures on the earth are mainly buried in the form of rock gold and sand gold. In addition, associated gold. After Celestial bodies movement, earth formation, volcanic eruptions, ancient mountain movements, magma spurts, and gold elements are entrained from the core, the rock gold is formed. The mountains were rich in gold form the alluvial gold during the process of sunshine weathering, thunder and lightning, violent storms, landslides, mudslides, flooding, and sedimentation in stable waters. That is, the primary gold mine undergoes weathering and geological action, is broken and transported by flowing water to a suitable place to form the alluvial mine (placer gold).

4. According to scientific measurements and inferences, about 2.6 billion years ago in the Archean, volcanic eruptions brought a large amount of gold elements from the core to the mantle and the crust along the fissures, followed by ocean deposition and regional metamorphism. The role of the formation of the original gold source. About 100 million years ago in the Mesozoic, due to the powerful role, the crustal deformation pleats, pleats exposed to the sea surface, gold material activation migration and accumulation, forming a gold ore field, that is, what we call Rock gold.

5. Natural gold is a kind of mineral formed in hydrothermal geological action. The natural gold deposit of natural gold is collectively called rock gold or vein gold. The primary gold deposits are irregularly distributed in the formation formed by hydrothermal geology. In the gold-bearing quartz vein, gold can coexist with minerals such as pyrite, arsenopyrite, galena and sphalerite.

6. In the rock-rich enrichment zone, after the rock is oxidized, many natural gold and superficial layers of rock gold are often left. After tens of millions of years of weathering and denudation, the rock becomes sand. Because of the stable nature of gold, it is dissociated into monomers, in the process of river water transportation, because of their heavier density, they are deposited in the stable water of the river, thus forming a sand gold mine. So far, the largest gold nugget discovered by humans weighs 280 kg, which is produced in California, United States.

7. The gold deposits formed during the change of nature can be roughly divided into three categories: rock gold deposits, sand gold deposits and associated deposits. In the world, the ratio of reserves of rock gold, associated gold and sand gold is about 70:15:15. Among them, the rock gold deposit can be divided into several genetic types: magmatic-hydrothermal type, metamorphic hydrothermal type, volcanic hydrothermal type, sedimentary metamorphism type, hot water leaching type and metamorphic conglomerate type.

8. The proportion of various types of gold deposits in the worlds total reserves is 56.2% of metamorphic conglomerate type, 12.4% of metamorphic hydrothermal type, 9.5% of associated gold, 8.9% of sand gold, magmatic-hydrothermal type and volcanic heat. The liquid type is 7.0%, and the hot water leaching type is 0.9%.

9. Globally, according to the geotectonic units produced by gold mines, they can be divided into four categories: ground shield metallogenic areas, platform and marginal metallogenic areas, geosyncline fold belt metallogenic areas and the Pacific Rim metallogenic belt. Among them, the gold reserves produced by the shields accounted for 25.627.8% of the worlds total reserves; the local Mesozoic activation zones of the ancient platform caprocks accounted for 1.11.3%, and the excellent ground trough areas accounted for 12.9-15.6%; The area of the ground trough, accounting for 1.11.2%; and the area of the ancient platform cover, accounting for 47.147.7%.

The grinding efficiency is the most important parameter to evaluate machine performance. This article discussed the factors that influence grinding efficiency including article size to mill machinemilling mediumslurry rheological propertiesunderflow ratiolinergrinding aid etc. The mill machine should be automatically controlled at a high level.

Ore grinding is a very important section in concentrators, which provides qualified grain grade materials for the subsequent mining processing operation. Grinding accounts for a great proportion of the basic construction investment of the concentrator, it is also consumed steel and energy high. According to statistics, the energy consumption of the crushing and grinding operation accounts for about 65% ~ 75% of the total energy consumption of the concentrator, and the steel consumption accounts for almost 100%. Therefore, it is of great economic and social benefit to correctly select the grinder mills, optimize the operation and improve the grinding efficiency.

In the most grinding process of the concentrator, the construction investment and production and operation cost of grinding operation is much higher than those of crushing operation, so it is necessary to reduce the grinding particle size as much as possible. The finer the grinding particle size is, the higher the grinding efficiency is, and the lower the steel ball consumption is. At present, more crushing and less grinding is one of the main principles of concentrator design and production. Take a gold mine as an example, reducing ore particle from -15mm to -10mm improve the grinding efficiency from 1150 tons per day to 1500 tons per day, and decrease the steel consumption and electric power consumption by 1.53kg/t to 1.1kg/t and 41.57kWh to 29.2kWh respectively.

Grinding mill medium is the main factor affecting grinding efficiency. In industrial production, the type, shape, size ratio and filling rate of grinding medium should be determined according to the grain size characteristics, hardness characteristics and product particle size requirements of ore materials.

The medium filling rate is the volume ratio of the medium and grinding cavity, moves in throwing and falling state in a ball mill. The throwing motion medium is used to smash large ore, and the medium of falling movement mainly plays the role of grinding. The filling rate of the fine grinding mill is about 5% lower than that of the coarse grinding. The motion state of the medium in the mill is related to the medium filling rate. There is friction force between the medium and the liner. When the filling rate and the friction force are large enough, the liner can bring the grinding medium to the height of the throwing point. It is also important to note that the medium filling rate should not exceed the limit. By the way, the larger the diameter of the ball mill, the lower the filling rate. For the rod mill, the filling rate is generally 10% lower than that of the ball mill of the same specification.

The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore. Large diameter steel ball help reduces grinding time thus improves grinding efficiency, in addition, putting some small steel ball to control the particle fineness effectively. In fact, the steel balls are continuously worn and the straight diameter is gradually smaller, so it is difficult to guarantee the ratio of the diameter of the steel ball to keep a stable level.

In the past few decades, researchers have done much work on finding the best shape of grinding medium. Practice shows that the ball mill can reach the finest grain with a lower cost under the regular grinding task requirements. Ball mill or rod mill, is there any else? Some researchers are focusing on a new type of grinding medium called spherocylinder in which has the combination of ball and rod. Experiments show that the spherocylinder grinding speed of the particle is bigger than 500m is faster than that of the ball mill. Besides, owing to the great features of selective grinding and fine grinding, the spherocylinder mill is definitely a good alternative shape to handle the grinding tasks.

Rheology is the science of studying the flow and deformation of objects. The slurry is often considered to be a fluid, which is deformed under stress. The concentration of slurry, particle shape, and particle size distribution are the important factors affecting the slurry rheological properties. From the analysis of the slurry rheological properties and the grinding speed, it can be seen that the grinding concentration affects the slurry liquidity, ore particle adhesion degree, and grinding efficiency. When the concentration/ thickness is too low, the slurry flows quickly and the adhesion degree on the medium is low, which weakens the impact and grinding force grinding mill apply on the ore material. Contrarily, high concentration, high adhesion may slow the flow speed, cause over grinding thus influence the production capacity. Practices show that only appropriate concentration can fulfill the grinding process at its best. For your reference, the grinding concentration of ball mill should better adjust to 72% 82%.

Regrinding sand is a kind of ore with unqualified particle size but close to qualified after grinding process, which is returned to the mills for regrinding. At usual, the grinding efficiency of the inner cavity is not balanced, the efficiency is gradually decreased from the feeding end to the discharging end because of the uneven distribution of the coarse grain along the axial direction. Based on the crushing theory, increasing the amount of regrinding sand does not increase the power consumption of the mill, but only speed up the slurry flow. In addition, thick and coarse regrinding speeding up the slurry flow can make the coarse grain distributed more evenly, thus improve the steel ball grinding performance and efficiency.

The liner plays the role of protecting the cylinder and end cover of the mill and lifting the grinding medium. The shape and material of liner have a great influence on the steel consumption of grinding. In addition to the traditional manganese steel liner, there are rubber liner and magnetic liner.

The consumption of mill liner accounts for a large proportion of the mineral processing cost. In recent years, some new wear-resistant materials have appeared. Among them, rubber liner has been well popularized because of its wear-resistant, long life, energy saving, noise reduction and so on. Because of the soft material, the rubber liner plays the role of cushioning on the cylinder. In the rough grinding operation, the impact of the steel ball will be cushioned, which reduces the production efficiency of the mill. But in the fine grinding task, the rubber liner can bring its superiority into full play.

The magnetic liner uses the magnetism of liner itself to adsorb a layer of ferromagnetic materials in the cylinder, including magnetic minerals, broken steel balls, etc., to form a protective layer of liner, so as to prevent the liner body from being worn out and prolong the life of the liner. Magnetic liner is mostly used for fine grinding.

Grinding aids are a kind of grinding auxiliaries, which can accelerate plastic deformation, promote crushing process, prevent condensation and adhesion. A small number of grinding aids can improve the grinding efficiency and reduce the power consumption of grinding.
