八一铜矿选矿厂处理的矿石为多金属硫化矿石。有用成分主要有铜、锌、硫、钡等。原设计的浮选流程为全浮选流程,以氰化物等作几种矿物分离的抑制剂。为了消除污染、提高生产指标,1974年采用亚硫酸钠、硫化钠的非氰工艺进行工业生产,同时将原流程改为铜硫部分混合浮选流程。1979年又成功地取消了亚硫酸钠,从而仅以石灰、硫化钠、硫酸锌有效地分离 The ore processed by Bayi Copper Mine concentrator is polymetallic sulfide ore. Useful ingredients are mainly copper, zinc, sulfur, barium and so on. The original design of the flotation process for the whole flotation process, with cyanide and other minerals for the separation of inhibitors. In order to eliminate pollution and increase production targets, non-cyanide process with sodium sulfite and sodium sulfide was used for industrial production in 1974, while the original process was changed to copper-sulfur mixed flotation process. Again in 1979, sodium sulfite was successfully removed and only lime, sodium sulfide, and zinc sulfate were effectively separated
