What Is Electrorefining? (with picture) - wiseGEEK

1-6-2020· Copper is recovered from sulfide ores this way, as part of the smelting process. People first began electrorefining metal in Europe in the mid-1800s, when just a few tons per day could be processed. Now, a plant in Chile, South American can electrorefine up to 1,700 tons per day of copper.

Electrolytic Refining - Meaning, Electrorefining of Copper ...

Copper is usually mined from its coal known as blister copper. It is about 98 to 99 per cent pure. However, the electro-refining process can easily make it 99.95% pure which makes it a good product to be used in electrical components. A block of impure copper is taken as an anode or positive electrode.
