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 mining includes heap leaching, solvent extraction, froth flotation processes. ... Once the process of mining, transporting, and crushing the ore to a golf-sized ball is accomplished, it is further processed and reduced to pebbles and then to sand like particles. It is then added with liquid to make it a slurry which is a combination of ...

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
