Copper extraction Wikipedia
Sulfide ores Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leachingThese ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits Supergene ores rich in sulfides may be concentrated usingMining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry In this month’s immining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at theMining Chemicals International Mining
Copper Mining and Processing: Processing of Copper Ores
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the differentAcidic reductive leaching is one of the best known and most widely employed chemical processes for beneficiating minerals of industrial interest Conventional acidic leaching with sodium dithionite (Na2S2O4), employed to bleach industrial minerals used in the production of ceramics, glassware, paper etc, does not always allow products of highChemical Leaching of Iron from Industrial Minerals AusIMM

explain leaching of alumina from bauxite Brainly
In the extraction of aluminium, the significance of leaching is to concentrate pure alumina(AL2O3) from bauxite ore Bauxite usually contains silica, iron oxide, and titanium oxide as impurities In the process of leaching, alumina is concentrated by digesting the powdered ore with a concentrated solution of NaOH at 473523K and 3536 barThe term metal (or metallurgical) leaching refers to the processes involved in separating useful metals from nonvaluable ore constituents The science behind these processes, while not a very glamourous topic, is important: beyond the obvious practical necessity of extracting the metals, leaching methods historically have left behind toxic waste products, so modern improvements representScience Break: Metal Leaching | Mar 2017 | CSEG RECORDER
