The Ancient History of Copper thebalance

Dec 30, 2018The ability to extract copper from ore bodies was well-developed by 3000 BC and critical to the growing use of copper and copper alloys. 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.

Copper Mine, Techniques,Ores, Mines, Occurence,

Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening

Extracting Ores Mining Of Mineral Resources Siyavula

In 1934 the first modern mining started with the extraction of apatite for use as a fertiliser. In 1946 a well known South African geologist Dr. Hans Merensky started investigating Loolekop and found economically viable deposits of apatite in the foskorite rock. In the early 1950s a very large low grade copper sulfide ore body was discovered.
