摘要
通过对金家河选矿厂工艺流程结构的技术改进和优化药剂制度，使铅精矿品位由原来４４．６４％提高到６６．２６％，铅精矿中含锌由１５．８０％降至７．４２％，锌精矿中锌的回收率由８６．５％提高到９３．７％。并降低了药耗，从而大大降低了生产成本。
By improving processing flowsheet and reagent programme in Jinjiahe Mine,lead concentrate is of 66.26%Pb upward from previous 44.64%Pb,of 7.42%Zn downward from previous 15.80%Zn,and the zinc recovery in its concentrate is of 93.7% upward from previ ous 86.5%.Meanwhile,reagent consumption and product cost were reduced obviously.
