The process of smelting is when industrial factories extract or smelter purer and more refined metals from ores. Metals like copper or lead are often extracted using this process from earth samples and deposits. Although smelting helps with metal productions, there are many disadvantages
Sulfide Ore. The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this smelting process the copper is about 99% pure.. Oxide Ore. The copper-bearing solution is collected and pumped to the extraction plant where it is purified.
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt

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 use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
