摘　　要：对采自云南红河、兰坪、东川及湖北大冶铜绿山的四个孔雀石样品,进行了分别使用D2(2、5——二硫酚——1、3、4——硫代二唑)及硫化钠作活化剂,黄药作捕收剂的单矿物浮选试验。研究了不同矿区孔雀石浮选基本行为间的差别、D2药剂作用规律及适用范围。对于以D2作活化剂,用黄药从氧化矿石中直接浮选未经预先硫化的氧化铜矿物新工艺的实践经验及结果也作了报道。Four pure malachite samples collected from Honghe, Lanping, Dongchu an and Daye respectively have been floated in a single flotation tube by butyl xanthate in the presence of chelating agent D2 ( 2,5-dimercapto-l ,3,4-thiodiazole ) or sodium sulphide as modifying agents. Some factors affecting floatability of different malachite samples have been studied.The investigation results show that various oxidized copper minerals can be floated from ores by xanthate when using D2 reagent as an activator without pre...
