copper extraction refers to the methods used to obtain copper from its ores. the conversion of copper consists of a series of physical and electrochemical processes. methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
as in all mining operations, the ore must usually be beneficiated (concentrated). the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals (such as chalcopyrite), th · text under ccbysa licensehow hydrometallurgy and the sx/ew process madeintroductionconventional copper extractionthe sx/ew processbacterial leachingconclusioncontacts and referencesalso in this issueconventionally, copper is recovered by a pyrometallurgical process known as smelting. in this process copper ore is mined, crushed, ground, concentrated, smelted and refined. the mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it. to be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as ch copper extraction by wet chemical methodthis. study reports on a n affordable and sustainable method f or the extraction of copper. this was. achieved through the use of a wet chemical method which makes use of hydrazones p repared inprocesses extraction, mining, smelting, refiningmining. the ore is removed from the ground in either open pit or underground mines. undergroundthe extraction of copper chemistry libretextsjul , · copper can be extracted from nonsulfide ores by a different process involving three separate stages reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to... concentration of the copper (ii) sulfate solution by solvent extraction. theestimated reading time 7 minscopper extraction process jxscmining copper extraction process plant includes jaw crushers, conveyor belt, vibrating screen, ball mill, jig machine, spiral classifier, mixing tank, shaking table
