Copper Electrolytic Refining Process In the electrolytic refining of copper, a thin sheet of highpurity 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. As current is passed through the solution, pure copper from the anodes is plated out ...

mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages. Separation of special copper ores such as those containing molybdenite or with high zinc or lead content (Canada) is also possible by flotation methods ...

Copper ore is extracted using two basic methods of mining open pit or underground mining. 3. Processing of Copper Ore . The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is ...

A similar recovery circuit is used to process gold and precious metals from anode slimes, typically from copper electrorefining. Depending on the origin of the materials, anode slimes often contain selenium and tellurium, which require removal. Several process routes are used, either soda ash roasting (fritting) or NaOH fusion with a suitable oxidant, followed by water leaching.
