Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

Apr 25, 2017· Smelting utilizes heat, and a reduction agent like coal, to extract the other elements from the metal according to Cornish Mining World Heritage. This results in a more refined metal product. Among the metals extracted by smelting are copper, lead, nickel, zinc, silver, cobalt, cadmium, gold, aluminum, and others.

Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2
