refining process of copper

Copper Refining - an overview ScienceDirect Topics

In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

Continuous electrolytic refining process of cathode

2019-5-1  Electrolytic refining is necessary to increase the purity of copper to 99.9% or even more and is a key process during the production process of high-purity cathode copper. The process consumes approximately 260–280 kWh of electricity energy to produce 1 ton of cathode copper in the industry, which accounts for 60–70% of the total energy consumption (Iikhchi et al., 2007). In many wet

Your Process Challenge for Copper - Heraeus

Blister copper is then casted into intermediary anodes which are further refined into copper cathodes (99.99% pure copper) through an electro-refining process. Cathodes are re-melted and processed into final end user products. Blister copper feed can be partially or fully replaced by secondary scrap to recycle end of life copper.

The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
