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。
As Dongshengmiao pyrite symbiosis sphalerite has high iron content, the single flotation process can not solve the problem of high iron impurities in zinc concentrate. In this study, a float-magnetic combination beneficiation process was used to further remove iron impurities in zinc concentrate by magnetic separation, which effectively enhanced the grade of zinc concentrate.
