Tin, and later copper, were the most commonly extracted tin mining continued long after the mining of other metals had become unprofitable.
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

London copper prices on Tuesday rose to their highest in nearly four weeks, as mining disruptions in major producing countries threatened supplies of the red metal. Threemonth copper on the
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
