During the refining procedure of the copper these elements are removed by using different techniques like selective vaporization and oxidation as well as refining electrolysis. Nearly all copper which is 'won' using the pyrometallurgical method (about 85 %) passes through the copper refining electrolysis.

The production of copper typically includes the following processes: Leaching Solvent Extraction Smelting Leaching There are two main leaching methods: heap leaching and in-situ leaching. Heap leaching is the most common method used in the U.S. When processing copper through heap leaching, vast quantities of ore and overburden are mined.

The final products of smelting and electrolytic refining are cathodes, cast often in the form of copper wirebars and cakes.* The casting are subsequently worked in various ways into wrought forms. Re-melted cathodes may also be cast into ingot bars suitable for the preparation of alloys. * See CDA Publication No. 52, Introduction to Copper .

sulfide ores undergo a five-step process: 1) the ore is crushed into a fine sand to loosen the copper minerals; 2) it is froth floated, where the sand is mixed with water and chemicals to make the copper particles water repellent; 3) air is passed through the mixture, allowing the copper minerals to attach to bubbles and float to the surface; 4) …

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 kW·h of electricity energy to produce 1 ton of cathode copper in the industry, which accounts for 60–70% of the total energy ...
