Magnetite and hematite are iron oxides however the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore which removes certain impurities carbon dioxide and other substances. Through this process ferrous oxide also oxidizes to ferric oxide.

Iron ore processing. After the iron ore has been prepared by crushing and grinding during ore extraction the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation. Subsequently the milled ores are lumped by sintering or pelletizing in order to
