The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech and are applied to a variety of materials including aluminum iron and copper.

These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals called gangue

Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten manganese nickel vanadium chromium) to strengthen and harden it making useful steel for construction automobiles and other forms of transportation such as trucks

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.
