摘要
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。
Gold, silver and copper in sulfide concentrates can be effectively recovers by means of separation of chalcopyrite and pyrite. The mechanism and approach of Cu - S separation has been discussed. In closed - circuit test under the condition of oxidation treating 15min, the chalcopyrite concentrate of 18. 02% Cu, 112g/t Au, 210g/t Ag have been obtained from sulfide concentrate containing 0. 67% Cu, 5. 01g/t Au, 17. 23 g/t Ag with the recovery ratio of 80. 5%, 74. 83%, and 40.72% respectively.
