摘　　要：研究了 pH和矿浆电位对新型小分子有机抑制剂ASC对黄铜矿和方铅矿的抑制作用的影响 ,结果表明ASC对方铅矿具有很好的抑制作用 ,对黄铜矿没有抑制作用。人工混合矿和实际矿石试验表明采用ASC能够代替重铬酸盐实现铜铅分离。The effects of pH and pulp potential on the depressing activity of new organic d epressant ASC to chalcopyrite and galena have been studied in this paper. Result s show that galena can be depressed well and chalcopyrite cannot be depressed by ASC. The results of artificial mixed ore test and actual ore test show that the separation of copper-lead can be separated well by ASC without adding dichromat e.
