Innovations: How Hydrometallurgy and the SX/EW Process
IntroductionConventional 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 copper-bearing 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 Wikipedia
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.

Dartmoor tin-mining Wikipedia
The tin mining industry on Dartmoor, Devon, England, is thought to have originated in pre-Roman times, and continued right through to the 20th century, when the last commercially worked mine (Golden Dagger Mine) closed in November 1930 (though it saw work during the Second World War). From the 12th century onwards tin mining was regulated by a stannary parliament which had its own laws.

Copper Smelting Process Furnaces Used, By-Products, and
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.
