Developments in chemical separation of iron ore - ScienceDirect www.sciencedirect.com science article Silicon and aluminum often occur in iron ores as quartz, aluminum sili e clay minerals, or gibbsite. These minerals, and phosphorus when it is present as a phosphate mineral, can be removed from the iron ore by physical separation methods Chapters 9 and 10 or flotation . However, when the minerals are finely divided and difficult to liberate, chemical separation techniques may be the most suitable method for reducing impurities. Extraction of Iron and Concentration of Ore - An Overview testbook.com blog extraction-of-iron 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. Coke is cheap and it provides both the reducing agent and heat source for the reaction. The most commonly used iron ores are Hematite, Fe2O3 , and magnetite Fe 3 O 4. Direct Biohydrometallurgical Extraction of Iron from Ore www.osti.gov servlets purlA completely novel approach to iron extraction was investigated, based on reductive leaching of iron by anaerobic bacteria. Microorganisms were collected from an anaerobic bog where natural seepage of dissolved iron was observed. This mixed culture was used to reduce insoluble iron in a magnetite ore to the soluble ferrous Fe sup 2 state.
