我矿选厂原设计为一段闭路磨矿、铅锌优先浮选流程。1973年增加了选锌尾矿再选萤石系统,完善了铅—锌—萤石优先浮选流程。选矿厂从1967年1月投产以来,一直是用氰化物和硫酸锌进行铅锌的优先浮选。氰化物用量为70~90(克/吨)。选矿厂废水外流,污染环境和水源,危害农副业生
My mine was originally designed for a closed-circuit grinding mill, lead and zinc preferred flotation process. In 1973, an additional fluorite tailing election system was selected, which improved the preferential flotation process of lead-zinc-fluorite. Since the ore dressing plant was put into operation in January 1967, it has been preferential flotation of lead and zinc with cyanide and zinc sulfate. Cyanide dosage of 70 to 90 (g / ton).
