extraction process iron ore hematite separation

Extraction of Iron &Concentration of Ore An OverviewSep 23, 2019 · The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke. Extraction of Iron from Haematite Grade 12 Science NotesHaematite ore being oxide ore is concentrated
