某高硫难选金矿金—疏分离试验研究

THE SEPARATION OF Au AND S IN A REFRACTORY GOLD ORE IN SICHUAN

四川某金矿为高硫含碳微细粒难选金矿,常规浮选所得精矿金品位只有25g/t左右。试验采用载体转移浮选技术,成功地解决了Au—S分离的技术难题,获得了金品位73.85g/t、回收率88.53％的金精矿,并综合回收了银、硫,提高了选冶厂经济效益。

There is a refractory gold mine with carbon- and sulfur-rich in Sichuan,obtained gold grade from its ores is only 25g/t when using conventional flotation. The separation of Au and S can be reached by carrier flotation described in this paper, a gold concentrate with grade of 73. 85g/t and recovery of 88. 53% can be obtained, and Ag and S can be recovered comprehensively.
