摘要
以电子电器废弃物作为原料,分别采用硫酸搅拌浸出-电解工艺以及硝酸处理铜浸渣结合氰化板卡脱镀-锌置换-王水提纯工艺,经浸出、置换、电积、析出等工序回收铜和金。
Copper and gold were recovered from electronic and electrical waste.The adopted processes are sulfuric acid stirring leaching-electrolysis and nitric acid treatment of copper leaching residue combined with cyanide plating off the board-zinc replacement-purification with aqua regia,respectively,including the process steps of leaching,replacement,electrodeposition and precipitation.
