摘要
某含金银高硫微细粒铜锌矿石中有用矿物粒度微细,黄铜矿与闪锌矿、方铅矿、毒砂关系密切,且硫高达21.44%。针对该矿石性质特点,试验探索了铜锌优先浮选、铜锌等可浮浮选、铜锌硫等可浮浮选、铜锌混浮—铜锌精矿再磨—铜锌分离、铜锌硫混浮—精矿再磨—铜锌硫分离等5种选别流程。试验结果表明:铜锌硫混浮—精矿再磨—铜锌硫分离流程适宜处理该矿石,其技术指标较好;同时,硫精矿(金银粗精矿)采用湿法工艺进行处理,也取得了良好的技术指标。
The useful mineral particles in one gold and silver contained copper-zinc ore are micro-fine with high content of sulfur, chalcopyrite is closely related to sphalerite, galena, and arsenopyrite, and the content of sulfur is as high as 21.44 %. In this paper, according to the characteristics of the ore properties, five processes are explored including selective flotation of copper and zinc, the flotation capacity of copper and zinc, the flotation capacity of copper, zinc and sulfur, mixed flotation of copper and zinc - regrinding of copper and zinc concentrates - separation of copper and zinc, mixed flotation of copper, zinc and sulfur - regrinding of concentrates - separation of copper, zinc and sulfur. The results show that the process of mixed flotation of copper, zinc and sulfur - regrinding of concentrates - separation of copper, zinc and sulfur is well suited for the treatment of the ore with good technical indexes;at the same time it a- chieves good technical indexes with sulfide concentrates （gold and silver roughing concentrates） subject to metallurgical treatment method.
