【摘要】 研究了多金属硫化矿浮选精矿加压酸浸过程及各种因素对浸出的影响。研究结果表明:在不苛刻的条件下经加压酸浸,多金属硫化精矿中锌浸出率可达99%以上,铜浸出率可达90%以上,而铅、银则98%以上进入浸出渣,元素硫产出率约70%。更多还原

【Abstract】 A process of acid leaching under pressure of polymetallic sulphide flotation concentrates and various influence factors on leaching is studied.The results show that more than 99% of zinc and more than 90% of copper in complex concentrates can be leached,while more than 98% of lead and silver left in the residue,and the recovery of sulfur is about 70% under an unfastidious condition.更多还原
