我矿的矿石系多金属硫化矿,主要金属矿物有方铅矿、黄铜矿、黄铁矿、闪锌矿等。生产中为确保铜铅精矿的质量,使用较多的氰化钠抑制黄铁矿、闪锌矿,虽在选硫作业中用了大量的硫酸铜,但由于黄铁矿被强烈抑制,难以活化,因此,大部分黄铁矿未能回收而弃于尾矿中。经分区定点取样化验表明,尾矿坝中的尾矿含疏5.85%,有回收价值。
Mine ore department of polymetallic sulfide ore, the main metal minerals are galena, chalcopyrite, pyrite, sphalerite and so on. In order to ensure the quality of copper-lead concentrates in production, more sodium cyanide is used to suppress pyrite and sphalerite. Although a large amount of copper sulfate is used in the sulfur-selective operation, pyrite is hard to be suppressed Activated, therefore, most of the pyrite fails to be recovered and discarded in the tailings. The sampling by sampling points shows that the tailings dam tailings containing sparse 5.85%, a recovery value.
