华南某铜铅锌矿浮选工艺研究

STUDY ON THE FLOTATION CRAFT OF COPPER-LEAD-ZINC ORE IN SOUTH CHINA

从试样的工艺矿物学研究入手,在查明试样化学成分、矿物组成、结构构造、粒度特性、嵌镶关系和赋存状态的基础上,依据矿石性质进行了探索性试验以确定试验方案。然后进行了详细的条件试验,确定最佳的工艺参数,并以闭路试验进行验证,取得了满意的分选指标,其中铜品位>24%、回收率>61%,铅品位>66%、铅回收率>90%,锌品位>55%、锌回收率>90%,为合理利用国家矿产资源,提供了详实的设计依据。

Learned from the study on mineralogy of the samples, a large amount of condition tests have been carried out on the basis of the chemical component, mineral composition, structure, storing states and mosaic relation of the samples to determine the optimum process and technological parameters. Then, the closed circuit trial have been taken and got a better classification index. And the concentrated copper ore： the concentrated lead ore： Pb〉66%, Pb recovery〉90% has provided the detailed design basis for making use ; the concentrated zinc ore： of country mineral resources Cu〉24%, Cu recovery〉61%; Zn〉55%, Zn recovery〉90%. It rationally.
