(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.
(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 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.
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.
