本专利系有关黄铜矿、方铅矿浮选分离的一种方法,将黄铜矿、方铅矿混合物,在低pH范围内氧化后,不加捕收剂的条件下,即能进行黄铜矿、方铅矿的浮选分离。原来采用浮选分离黄铜矿和方铅矿时,为达分离的目的,需要加黄药类型的捕收剂,并用氰化物抑制黄铜矿,或者用二氧化硫或铬酸盐抑制方铅矿。然而,根据作者进行的有关黄铜矿、方铅矿浮选分离的种种研究结果,认识到,如果将 This patent is related to chalcopyrite, galena flotation separation of a method of chalcopyrite, galena mixture, after oxidation in the low pH range, without the collector under the conditions that can be yellow Copper, galena flotation separation. The original separation of flotation of chalcopyrite and galena, for the purpose of separation, the need to add xanthate type collector, and use of cyanide inhibition of chalcopyrite, or sulfur dioxide or chromates inhibit galena. However, according to various studies conducted by the authors on chalcopyrite and galena flotation separation, it is recognized that if
