This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper.
While copper is produced around the globe, production is largely localized to select regions, specifically Latin America; in 2017, Latin America accounted for 42% of global copper mine production. Asia was the second largest producer at 17%, followed by North America and Europe at 13% each, Africa at 10%, and Oceania with 5%.
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of

Copper mining also provides many valuable by-products that can be used in advanced material applications. For example, it is responsible for the production of almost 500,000 tonnes of cobalt, molybdenum, rhenium, selenium, tellurium and rare earth elements, in addition to volumes of silver, tungsten, gold, lead and zinc.
2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction, described above. Dilute acidic solutions are introduced to the copper-bearing ores, causing dissolution of soluble copper minerals (Table 1) remaining in the leached cap and underlying enrichment blanket.
Sep 26, 2019· Currently, about 80% of global copper production is extracted from sulfide sources. Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore …
Apr 09, 2010· We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.
Also, the numerous stages of the copper production process – from leaching and flotation to smelting and casting – means mineral-bearing material is mixed and moves around a lot, not just within mines but between mines and smelters too.
Dissolved copper from the anode is electrolytically deposited on the stainless steel cathode plate. After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with grade of 99.99%) as a final product.
