Most of China's barite mines use open-pit mining. During the mining and washing process, many muddy waters are produced, polluting rivers, and polluting farmland during the rainy season. Since most of the mines are mined by township and village enterprises, and there are many mining points scattered, direct treatment is not easy to implement and it is difficult. Guangxi Petrochemical Department adopts centralized washing method and deducts environmental protection when paying mining producers' mine money. The treatment fee shall be used centrally and uniformly by the relevant departments of the county. According to the flow of water, the simple overflow dam in the downstream building will be discharged through the overflow port after clarification, which basically solves the problem of muddy water pollution.
The barite mine mined underground, the waste water discharged from the pit is tested, the water quality is non-toxic and harmless, and it is free to be discharged without special treatment. The three wastes discharged from the production of strontium salt contain toxic components, which are seriously polluted by the environment and must be treated.
