研究了从硫精矿（黄铁矿产品）中综合回收金银铜，探讨了实现铜硫分离的机理 与手段．在原硫精矿中Ｃｕ、Ａｕ、Ａｇ分别为０．６７％、５．０１ｇ／ｔ、１７．２３ｇ／ｔ的情况下，当氧化时间 为１５ｍｉｎ时，可较好地实现铜硫分离．闭路试验获得βＣｕ＝ １８．０２％、βＡｕ＝ １１２ｇ／ｔ、βＡｇ＝ ２１０ｇ／ｔ、εＣｕ＝８０．５０％、εＡｕ＝７４．８３％、εＡｇ＝４０．７２％的铜精矿。 The recovery of gold, silver and copper from pyrite (pyrite products) was studied, and the mechanism and means to achieve copper and sulfur separation were discussed. When Cu, Au and Ag were 0.67%, 5.01g / t and 17.23g / t, respectively, the separation of copper and sulfur was achieved when the oxidation time was 15min. The closed circuit test results in copper concentrates with βCu = 18.02%, βAu = 112 g / t, βAg = 210 g / t, εCu = 80.50%, εAu = 74.83% and εAg = 40.72%.
