【摘要】：为解决铜钼分离浮选后钼精矿中铜含量较高的问题,以河南某选厂钼精矿为研究对象,采用超导磁选方法进行细粒黄铜矿分离试验研究,重点对脉动冲次、分散剂用量、背景磁场强度及聚磁介质直径进行了试验优化,取得理想的分选指标。最终确定采用"分级—细粒级超导磁选"工艺,原钼精矿中铜含量由0.69%降至0.193%,磁选精矿产率为93.16%,钼的总回收率为95.96%。
[Abstract]:In order to solve the problem of high copper content in molybdenum concentrate after separation and flotation of copper and molybdenum, the superconducting magnetic separation method was used to study the separation of fine chalcopyrite by using superconducting magnetic separation method. The magnetic field intensity and the diameter of the magnetic medium are optimized by experiments, and the ideal separation index is obtained. Finally, the technology of "graded and fine grained superconducting magnetic separation" is adopted. The copper content in the original molybdenum concentrate was reduced from 0.69% to 0.193. The yield of magnetic concentrate was 93.16 and the total recovery of molybdenum was 95.96B.
