置换沉淀就是一种金属被另一种金属还原沉淀,它是提取冶金中所用的最古老的单元操作之一,现在仍是很多金属回收和纯化流程的重要部分。目前,置换沉淀铜法在铜流程中的应用日渐减少,全世界的矿产铜几乎全部都是用浮选、熔炼、电解精 Displacement, a metal that is reduced by another metal to precipitate, is one of the oldest units used in extraction metallurgy and is still an important part of many metal recovery and purification processes. At present, the replacement of precipitation of copper method in the process of reducing the use of copper, almost all of the world’s mineral copper is flotation, smelting, electrolytic fine
