摘要
由于东升庙硫铁矿共生闪锌矿的含铁量高，所以采用单一浮选流程不能解决锌精矿铁杂质含量高的问题。本研究采用浮一磁联合选矿流程，以磁选法进一步去除锌精矿中的铁杂质，有效地提高了锌精矿的品级。
The problem of high iron content in zinc concen-trate can not be resolved by single floatation flowsheet because theiron content of sphalerite contaminated in pyrite is high. A com-bined flowsheet of floatation - magnetic separation is adopted nthe test to further remove iron from zinc concetrate. The grade ofthe zinc concentrate is improved effectively.
