Hydrometallurgical stepwise recovery of copper and

2020-11-1  A new process for recycling zinc and copper from the smelting slag of waste brass was investigated in this study. The zinc and copper present in the smelting slag were dissolved in a ZnCl 2 –NH 4 Cl solution system. To recycle copper, the lixivium was purified by a novel method termed as electrochemistry and chemistry synergetic (ECS) purification.

Copper Purification Process Electrolytic Copper

2017-12-29  Copper Electrolytic Refining Process In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

Review of Copper Recovery Methods From

Addition of 10-20 percent copper sulfide reduces up to 10 percent lead and 8 percent tin in copper residue. Recovery of copper is 96.2% with combination of acid leaching from the generated slag. Recovery of copper from pickling solution. Like every common metal, brass also has a
