Copper can be extracted from non-sulfide 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 produce a very dilute copperii sulfate solution.Concentration of the copperii sulfate solution by solvent extraction.
A hydrometallurgical process for the production of metallic copper comprising a reduction stage in which materials containing copper-iron sulfide ore concentrates are introduced into an aqueous chloride solution containing cupric chloride to solubilize part of the copper in said materials and reduce a substantial portion of the cupric chloride to cuprous chloride, the total.
F our big mines dominate zambias copper production, complemented by several smaller players who also play an important role.All the mines are backed by a wide range of respected international investors.The zambian government, through its investment-holding company zccm-ih, is a minority shareholder in nearly all of them and is, in effect, the biggest shareholder in zambias mining.

Worldwide production of aluminium in 2010 was 41.4 million tonnes.Using the figures above this means that 621 billion kilowatt hours of electrical energy were used in the production of aluminium.To put that in perspective, the total world production of electrical energy was 20261 billion kilowatt hours, meaning that more than 3 of the world.
Copper is a chemical element with the symbol cu from latin cuprum and atomic number 29.It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling.
Each year in the usa., nearly 45 as much copper is recovered from recycled material as is derived from newly mined ore.Excluding wire production, most of which uses newly refined copper, nearly two-thirds of the amount used by copper and brass mills, ingot makers, foundries, powder plants and other industries comes from recycled scrap.
