富含铜、铅离子铅锌矿浮选研究

Study on Flotation of Lead-Zinc Ore Rich in Cu^(2+) and Pb^(2+)

针对矿石富含铜、铅离子以及锌矿物主要以铁闪锌矿形式存在的特点 ,试验采用硫化钠预先沉淀矿浆中的Cu2 + 、Pb2 + 等离子 ,不仅简化了药剂制度 ,而且提高了锌精矿的品位和回收率 。

Based on characteristics of some minerals which co ntains much Cu 2+ and Pb 2+ and zinc in mineral is mainly in the form of marmatite,the sodium sulphide is applied for preliminary precipitation of Cu 2+ and Pb 2+ in pulp.By using this method,the technical indexes such as the grade and recovery of zinc in concentrate.
