摘要
某低品位铜锌硫化矿嵌布粒度细,共生关系复杂,磁铁矿和磁黄铁矿含量高,主要目的矿物易选难分、选别难度大。采用"磁选脱铁-优先浮铜-锌硫混浮-锌硫分离"的工艺流程选别该矿石,在新型锌抑制剂SJ的作用下,实现了铜锌的高效分离;当原矿含铜0.089%、含锌0.53%时,实验室闭路试验获得了铜品位20.12%、锌品位5.24%、铜回收率为75.45%的铜精矿和锌品位为53.68%、铜品位0.96%、锌回收率为78.97%的锌精矿,为该矿石的选别利用提供了技术支持。
A low-grade copper-zinc sulfide ore has fine intercalation particle size, complex symbiosis relationship, and high content of magnetite and pyrrhotite, and the main purpose minerals are easy to select but difficult to separate. Therefore, the process of magnetic separation of iron removal, priority floatation of copper, zinc-sulfur mixed floatation, and zinc-sulfur separation was used to separate the ore. Under the action of the new zinc inhibitor SJ, the efficient separation of copper and zinc is realized. When the copper content in raw ore is 0.089% and zinc content is 0.53%, by the laboratory closed circuit test, the copper concentrate with copper grade of 20.12%, zinc content of 5.24% and copper recovery rate of 75.45% is obtained, as well as zinc concentrate with zinc grade of 53.68%, copper content of 0.96% and zinc recovery rate of 78.97%. The study can provide a technical support for the beneficiation and utilization of the ore.
