    Extraction Of Iron SlideShare. May 22, 2009 The main ores are i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide Fe2O3). o The iron ore contains impurities, mainly silica (silicon dioxide). o Since iron is below carbon in the reactivity series, iron in the ore is reduced to iron metal by heating with carbon (coke).Jul 07, 2020 Through this quartz mining process, the high-quality refined quartz sand (silicon dioxide ≥99.8 , iron oxide ≤0.023 , aluminum oxide ≤0.05 , titanium dioxide ≤0.02 ) can be obtained, which has reached the requirements of primary optical glass sand, and the yield of fine quartz sand is as high as 73 , while the yield of rod friction.And other qualified concentrates were gained by magnetic separation - fine screen - magnetic separation, then oversize material returned to thickening and magnetic separation for reprocessing.
