摘　　要：河南中原黄金冶炼厂采用卡尔多炉处理铜阳极泥,其产生的熔炼渣中含有金、银、硒、碲等稀贵金属,具有很高的回收价值。采用浮选工艺对熔炼渣进行富集回收,考察了磨矿细度、捕收剂、调整剂等因素对浮选指标的影响。结果表明:闭路试验可获得品位为金2 133. 51 g/t、银38 756. 18 g/t,回收率为金94. 54%、银86. 69%的混合精矿,同时硒、碲也得到一定程度的富集,试验结果为熔炼渣的回收利用提供了依据。Henan Zhongyuan gold smelter uses Kaldo converter to deal with copper anode slime,which contains rare and precious metals worth recovery like gold,silver,selenium and tellurium.The slag produced is enriched and recovered by flotation and the influence of grinding fineness,collector,modifier on flotation index is investigated.The results show that closed circuit can obtain a blended concentrate with gold grade 2 133.51 g/t,silver grade 38 756.18 g/t,gold recovery rate 94.54%and silver recovery rate 86.69%.At the same time selenium and tellurium are enriched to some extent.The experimental results provide basis for smelter slag recovery and utilization.
