How minerals are extracted from earthIn a previous lesson we learned about minerals which are inorganic compounds such as ores like copper and precious stones like diamonds.

If a metal is less reactive than carbon it can be extracted from its compounds by heating with carbonCopper mostly occurs as sulfide ores which are heated in air.

How much copper has been found in the world?.

Leaching is the process to extract pure copper from a low grade oreLeaching is the process of extracting substances from a solid by dissolving them in a liquid in this process the ore is dissolved in liquid but not impuritiesThen the copper solution is reacted with iron to get pure copper reduction processC u 2 h 2 → c u p u r e.

The resulting cement copper was then processed in a smelter and electrolytic refinery to produce high-purity copperBy the use of the sxew process copper can now be extracted away from the iron and other impurities in solution and further purified and reduced to metallic metal by electrolysis without ever having to be melted.

This process is used for the extraction of copper from low grade sulfide oreIn this process the crushed and ground ore in bulk about 100000 tons is exposed to air and water in big tanksThe air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.
