Product Description

Small Scale Portable Modular Gold Processing Plant for Alluvial Deposits
Small Scale Portable Modular Gold Processing Plant for Alluvial Deposits
The following situations or difficulties are common in plenty of small gold mines:
  1. Geological exploration is inadequate, proven resource reserves are small, scattered veins are narrower or shorter, which are not suitable for large-scale mining;
  2. The mine owners lack sufficient funds to invest in medium and large-scale mines and need to make profits from small-scale mining and processing.
  3. The mine traffic is inconvenient and not suitable for large-scale heavy equipments transportation, materials and power supply are shortage;
  4. The lack of water resources in mining areas can not meet the continuous demand of water for medium and large-scale plant production;
  5. There are a large number of artisanal or small-scale miners in the mining area who generally use sluice boxes, amalgamation with mercury or other old processing to recover gold, which is inefficient, low recovery, harms health and environmental pollution.
  6. Some mine owners hope to transfer their processing plants to another mining area after a few months or one or two years of production.They do not want to repeat to set up new plants.
  7. Small-scale mine owners hope to obtain the best general solution to recover gold directly by quickly setting up a processing plant for production and minimizing tedious work;
  8. Many small-scale artisanal miners in the mining area hope that there will be a small-scale processing plant in the area.They send ores for processing in the plant for making better profits than the original processing by their selves.
  9. Some mine owners who have mines with large reserves of resources worry that the risk of directly establishing large-scale processing plant is too high.They need to establish a small-scale plant as pilot to verify the actual processing effect and conduct economic evaluation, so as to provide the basis for final decision-making.
  10. Previously processed tailings still contain valuable gold.The mining investors want to quickly build a small-scale processing plant with low investment to recover as much gold as possible from tailings under the lowest production costs.
Aiming at the demand of small-scale gold mining and processing, HZE design and manufacture the small-scale modular gold processing plants to recover gold from rocks, quartz veins, alluvial deposits or tailings by gravity separation, flotation, cyanidation or combination processing. Excellent solutions, advanced technology, complete functions, reliable and safe equipment, compact structure, unconditional installation locations, low-cost investment and simple construction make the modular processing plants become the shining stars of flexible, fast and efficient recovery of gold  and be favored by more and more mine owners.

The small-scale modular concentrator has achieved the following targets:
(1) Maximizing the utilization of mineral resources ensures high recovery and economic benefits;
(2) The advanced technology and processing are adopted to get rid of the harmful chemicals such as mercury completely and protect human health and natural environment;
(3) Energy, water and consumables are saved, the number of operators is reduced, the capital of investment and the cost of production are decreased.
(4) Installation is fast, operation is easy, running is reliable, and different functional modules are combined freely to achieve the maximum recovery of gold.
(5) Minimal civil work requirements and the construction period reduced very much.
(6) It is easy to containerized, shipped or transferred to another location and reassembled, even in the most remote locations in the world.


General Functional Modules
Small Scale Portable Modular Gold Processing Plant for Alluvial Deposits
Crushing Module

The rocks are crushed to the qualified particle size for grinding.The module is composed of hoppers, crushers, belt conveyors, feeders and so on.
The ores are usually crushed in two stages. According to the actual situation of the site, the primary crusher can be mounted in the mining area or the processing plant. The crusher is usually driven by a diesel engine if it is located in the mining area.

Grinding and Classification Unit
The closed-circuit grinding and classification system consisting of the ball mill and spiral classifier can liberate ore into the suitable particles for recovering gold. The unit can be adjusted to a closed-circuit system consisting of the ball mill, slurry pump and hydrocyclone if the customer demands.
The grinding and classification unit is amounted in the whole steel frame.


Processing Modules
It is selected the general modules and the special modules to combine together to achieve maximum gold recovery.

The commonly used special modules are gravity concentration module, flotation module and cyanide leaching module.

Gravity Concentration

If the gold ore has much granular gold (free gold) which can be to recovered by gravity to get a good benefit.
The ore is the grinding circuit after the stage of crushing and screening.If the raw ore contains some sticky slime and clay, the washing equipment such as the trammel screen or scrubber should be added into the crushing circuit.
Commonly used gravity equipment includes jigs, centrifugal concentrators and shaking tables. The sluice boxes are also used as effective facilities for efficient gold recovery.
The concentrate obtained by gravity can be produced the ingots by pyrometallurgy or hydrometallurgy.
The tailings of gravity can be pumped to the tailings impoundment or sent to the circuit of flotation, cyanidation or others to recover the residual gold as much as possible.

Froth Flotation
The gold ore sent to the processing plant will be crushed, screened, and ground, then the slurry enters the flotation stage generally. Flotation acts to sulfides and free gold normally, and it is necessary to use appropriate chemicals for slurry mixing and gold recovery by flotation. Generally the flotation circuit includes rougher, scavenger and cleaner to obtain a satisfactory concentrate.
If the ore contains some free gold particles, gravity separation equipment is generally added to the grinding circuit to recover the particulate gold.
If the ore contains much oxides, some gold is difficult to recovered by flotation. It is possible to combine flotation and cyanidation to increase recovery.

Cyanide Leaching
Generally sodium cyanide is used for leaching gold from ground raw ore or re-ground concentrate to obtain pregnant solution. Gold in pregnant solution is adsorbed by activated carbon or precipitated by zinc.
Usually heap leach or vat leach extracts gold from low grade ore. Raw ore is leached on pad to get pregnant solution after crushing and agglomerating. Activated carbon absorbs gold out of pregnant solution.
Gold loaded carbon is processed by stripping and electrowinning to get gold slime. Pregnant solution is precipitated by zinc to produce gold slime.
The gold mud is smelted to cast gold ingots after a series of processing: pickling, separating other metals, washing, filtering, drying, etc. The purity of the merging gold ingot can reach over 97%. If purification is required, further processing is required.



Water Supply Module
It is composed of the water tanks, water pumps and water supply pipeline. The optimized water balance is achieved by the controlled the utilization rate of water.

Power Supply Module
It is composed of the diesel generators, distribution devices and the starting panels and so on. The module is suitable for the areas with inconvenient traffic and shortage of the power grid.
