• Reduction is the process of removal of oxygen for extraction of metals from their oxide ores. The common reducing agents used for reduction of metal oxides are: Carbon monoxide, Carbon, Hydrogen.

What are "ores"?

An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide.

• Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well. Ores are commonly oxides, for example:

• bauxite (Al2O3)
• haematite (Fe2O3)
• rutile (TiO2 )

. . . or sulfides, for example:

• pyrite (FeS2 )
• chalcopyrite (CuFeS2 )

( I hope its correct, if not ask you Teacher what is correct answer ! )
