【摘要】 通过调整矿浆电位（Ｅｐｔ）和矿浆ｐＨ．优先进行黄铜矿的自诱导浮选，实现了天然矿石中的铜－砷、铜锌的分离。对广西珊瑚矿的铜砷硫化铁矿进行了微捕收剂浮选分离的研究，与常规的黄药捕收浮选相比．自诱导优先浮选的铜精矿品位较高，表明自诱导浮选和分离过程有更高的选择性．为铜精矿降硫、砷和锌提供了新途径。更多还原

【Abstract】 he separations of copper from arsenic and copper from zinc were achieved through giving pri-ority to the self-induced floatation of chalcopyrite by adjusting the electric potential and pH of the pulp.the copper content of the concentration from the prior self-induced floatation is higher than nor-mal floatation,The self-induced floatation provides anew way to decrease sulphur,ansenic and zinc in Copper concentration.更多还原
