以控制电位氯化渣为原料,用加压浸出法从铜镍矿中提取贵金属是我国某资源综合利用项目之一,系统的工艺试验结果表明,加压浸出可以取代四氯乙稀脱硫及浓硫酸浸煮两个工序,它具有周期短、消耗低、产出的贵金属品位高等特点,是一种有发展前途的新工艺。但 Controlled potential chlorine residue as raw material, extraction of precious metals from copper-nickel ore by pressure leaching method is one of the comprehensive utilization of resources in our country. The results of process test show that pressure leaching can replace the desulfurization and concentration of tetrachlorethylene Sulfuric acid digestion two processes, it has a short cycle, low consumption, the output of precious metals high grade, is a promising new technology. but
