- Process Of Copper Mining
Copper is a chemical element in the periodic table with the symbol Cu (from the Latin word cuprum, meaning 'metal of Cyprus,' where it was mined during the Roman era).Copper has an atomic number of 29 and atomic weight of 63.54 grams per mole. It is an element in Group 11 of the periodic table, sharing many properties with silver and gold.

Copper occurs in nature in the form of sulphide and oxide ores, salt minerals and as native copper. It is the second most used non-ferrous metal in industry (Boulamanti and Moya, 2016).According to the United States Geological Survey (USGS), the 2019 global annual copper extraction was about 20 million tons (Fig. 1).The highest annual …

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.
