我矿地处科尔沁草原,属于半农半牧区,对于水源污染造成危害,是一个必须认真解决的问题。同时,矿石含银较高,也应该避免使用氰化物,使贵金属少受损失。几年来,我们采用碳酸钠调整矿浆pH值、硫酸锌抑制闪锌矿优先选铅的工艺流程,得到较 My mine is located in Horqin grassland, which belongs to the semi-agricultural and semi-pastoral areas. It is a problem that must be solved seriously to cause harm to water pollution. At the same time, ores are high in silver and cyanide should also be avoided, resulting in less loss of precious metals. Over the past few years, we use sodium carbonate to adjust the pH of the pulp, zinc sulfate inhibition of zinc pickle priority process, get more
