How Was Copper First Extracted From Its Ore. This process is known as SX-EW solvent extractionelectrowinning. Lake Van in present-day Armenia was the most likely source of copper ore for Mesopotamian metalsmiths who used the metal to produce pots trays saucers and drinking vessels. This trickles slowly through the ore dissolving copper to form copper sulfate. Copper is found in the free metallic state in nature.
Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulfuric acid to. It is found in ore deposits around the world. The copper is then recovered by electrolysis. The different steps in extraction of copper are. First the ore is treated with dilute sulphuric acid. Copper can be obtained from low grade from low through the process of leaching using acid or bacteria leaching processes in which ore is treated with a suitable reagent which dissolves ore but not the impurities.
The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized.
Ores near the surface can be quarried after removal of the surface layers. Ores near the surface can be quarried after removal of the surface layers. This native copper is the material that humans employed as a substitute for stone. The ore being sulphide ore is concentrated by froth floatation process. Coper Old English and copper were derived from this the later spelling first used around 1530. It can be formed just heating it in air.
