哲兹卡兹干矿床的铜—铅矿石,共铜含量的90％左右以辉铜矿和斑铜矿两种矿物产出,这在世界上是独一无二的。在已知的矿床中,无论是苏联的、还是其他国家的,都还没有发现类似的矿石。由于哲兹卡兹干矿石的矿物组成是这样的特殊,采用先混合浮选以后优先分选这种传统的工艺流程(见图1、图2),用氰化锌法分离铜—铅混合精 About 90% of the copper-lead ore in the Zhezkaz dry deposit is produced in two minerals, chalcocite and bornite, which are unique in the world. In the known deposits, no similar ore has been found in the Soviet Union or in other countries. Since the mineral composition of Zhezkaz dry ore is so special, the traditional process of first sorting after mixed flotation (see Fig. 1 and Fig. 2) is adopted to separate the Cu-Pb mixed solution with zinc cyanide
