处理氧化铜矿的方法虽不尽一样,但国内外大多采用常规的先硫化后浮铜的工艺方法。其中伴生金银在浮选铜的过程中自然富集于铜精矿中.但该法的弊病在于它使矿石中的自然金、自然铜及其部分硫化物在大量硫化剂作用下损失于尾矿中.优先选金工艺特点是基于硫化前优先选出上述易浮的自然金、铜等矿物,因而使金明显富集,得到含金165.67g/T的金精矿,并使金、铜回收率分别提高14.75%、9.51%.
Although the method of processing copper oxide is not the same, but at home and abroad most of the conventional use of the first after the floatation of copper process. Among them, the associated gold and silver are naturally enriched in the copper concentrate during the flotation of copper, but the drawback of this method is that it causes the loss of natural gold, natural copper and some of its sulfide in the ore under the action of a large amount of curative Mine.Preferential gold process is characterized by preferential selection of the above-mentioned pre-vulcanization of natural gold, copper and other minerals, so that gold was significantly enriched to obtain a gold content of 165.67g / T gold concentrate, and gold, copper The recovery rate increased by 14.75% and 9.51% respectively.
