Extraction and Refining of the Platinum MetalsFrom Ore to Finished Product copperorg

Electro Refining Operations Copper anodes from the converter process are dissolved electrolytically using an acid copper sulphate solution as an electrolyte The products of this operation are pure copper cathodes and an anode slime which Platinum Metals Rev 7 Copper From Beginning to End Copper is a major metal and an essential element used by man It is found in ore deposits around the world It is also the oldest metal known to man and was first discovered and used about 10 000 years ago And as alloyed in bronze copper tin alloy about BC was the first engineering material known to man

How Hydrometallurgy and the SX/EW Process Made Copper the Lead processing Refining Britannica

The impure copper is then purified by electrolytic purification to pure copper while the iron oxide is disposed of as slag Typically in this process there is more sulfur dioxide produced by weight than there is copper Rather than discharge the sulfur dioxide into the air as was once the practice the sulfur dioxide is captured and Lead processing Lead processing Refining To remove and recover remaining impurities from lead bullion either pyrometallurgical or electrolytic refining is used the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy The Parkes zinc desilvering process is the most widely used

Electrorefining of CopperCopper processing Roasting smelting and converting

Fire refined copper is adequate for noncritical applications such as water tubing bar stock or ingots for alloying Copper intended for electrical uses however is produced by electrorefining or sometimes electrowinning techniqu Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stageThe final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels This oxidation reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 995 percent copper that is required for electrolytic refining
