In the process of gold production, the tailings generally deposited in the treasury as a mixture of wastewater and solid form of slag tailings,and occupated of a large number of land，at the same time, wastes valuable mineral resources, seriously affecting the production environment, and tailings still has a big security risk, the residue of tailings has more dangerous on the ecological environment.
Fu Wei Heavy puts out tailings processing technique which proposes for the characteristics and the actual situation of gold production in northern arid areas, in the gold cyanidation process, with the core of dealing with the tailings filter, this technique can solve problems of the low rate of gold leaching, excessive discharge drainage cyanide concentration and serious tailings discharge.
The production of practice shows that:
1.Saving about 127,000 cubic meters of water per year.
2.Recycle 16.39 tons of cyanide and improve resource recovery.
3.Significantly improved the dressing recovery rate, 724,000 yuan in revenue.
4.Savings in the cost of sewage treatment and disposal of total 1,003,000 yuan.
Integrated technology, that conbined tailings filter process technology with high-pressure fresh water wash tailings, has great value and prospects of promotion in the course of China's gold production.
