复杂铜铅锌混合精矿的冶炼分离研究

Study on Smelting Separation of Complex Copper Lead Zinc Mixed Concentrate

在处理低品位多金属硫化矿时,为了提高有价金属的总回收率,往往采用全混合浮选工艺而得到含多种有价金属的混合精矿。文章针对此种混合精矿的特点,在总结前人研究的基础上,通过多次探索及扩大化试验,得出了冶炼分离此种混合精矿的最佳工艺,并确定了适合工业化生产的工艺参数。

When dealing with low - grade polymetallic sulfide ore, in order to improve overall recovery of valuable metals, it often uses full hybrid flotation process to get mixed concentrate containing a variety of valuable metals. In view of the characteristics of this mixed concentrate, based on the previous studies, the optimum separation of such mixed concentrate smelting was abtained through multiple test results and the process parameters were identified suit- able for the industrial production.
