根据对东川地区各种泥质氧化铜矿石长期试验室浮选试验的结果,就如何正确使用浮选剂的问题进行了讨论.笔者认为,抑制剂的选择,应该从矿石的矿物组成出发,六偏磷酸钠对汤丹钙、镁型矿石脉石的抑制效果比硅酸钠好,而羧甲基纤维素则对澜泥坪矿碳质脉石及粘土质矿泥,显示了良好的抑 Based on the results of long-term laboratory flotation tests on various muddy copper ores in Dongchuan, the issue of how to properly use flotation agents is discussed.In the author’s opinion, the choice of inhibitors should start from the mineral composition of the ores , Sodium hexametaphosphate on the Tang Dan calcium, magnesium ore gangue inhibition effect better than sodium silicate, and Carboxymethyl cellulose Lanlanping carbonaceous gangue and clay mud, showed a good Suppressed
