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 differentThis chart shows how sulfuric acid is used to extract copper The main difference between this and the ‘pyroprocessing’ of sulfide ores is that no heat is used The pictures below show the process sequence 1 Crushed ore is carefully dumped into a leakproof lined valley created in an open pit mine Crushed oreMining and Extraction: Oxide Ores processes for

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 usingJ Hammerschmidt, A Charitos, in Gold Ore Processing (Second Edition), 2016 434 Sulfuric Acid Plant The sulfuric acid plant can be divided into three main sections: drying and adsorption, SO 2 converter with gastogas heat exchangers and tail gas scrubber The plant uses the 3 + 1 doubleabsorption systemSulphuric Acid an overview | ScienceDirect Topics
Uranium processing Leaching | Britannica
Uranium processing Uranium processing Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process Acid leaching is commonly performed by agitating an oreSulfuric Acid is a liquid that is used to create batteries and processing unitsIt is converted, by the chemical plant, from sulfur, water, and iron platesIt must also be piped into electric mining drills to mine Uranium ore Optimal Ratio The optimal ratio for Sulfuric Acid production is two Sulfuric acid Chemical plants for every five Sulfur Chemical plantsSulfuric acid Factorio Wiki
Heap leaching Wikipedia
This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more commonMetallurgical ContentParting GoldSilver Alloy with Sulphuric AcidGoldZinc AlloysGold, Silver, and SodiumEffect of Tellurium on PartingParting of Gold and Silver CommerciallyThe Gutzkow Refining Process Pure silver is readily attacked by strong hot sulphuric acid of SG 1815, or about 90 per cent, strength The reaction which takes place may be represented as follows: 2Ag + 2H2 SO4 = Ag2 SO4Refining Gold with Sulphuric Acid
