我矿是1977年1月投产的小矿山。选矿厂采用混合浮选工艺流程,用氰化钠一硫酸锌作为闪锌矿的抑制剂,铅锌混合精矿经浮选分离后得到铅、锌两种精矿。为消除氰化物的污染,我们遵照英明领袖华主席关于“工业要发展,污染问题要认真解决”的指示,于去年4月着手其他抑制剂的试验。 Mine is a small mine put into operation in January 1977. Concentrator using flotation process, using sodium cyanide zinc sulfate as an inhibitor of sphalerite, lead and zinc mixed concentrate by flotation separation of lead and zinc concentrate. In order to eliminate the pollution of cyanide, we conducted the trial of other inhibitors in April last year in compliance with the directive of Chairman Hua, the wise leader, on the “industrial development, pollution problems to be seriously resolved.”
