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.
