Q. Name the Oxide Minerals?
These minerals consist of oxides of metals, which are formed either by oxidation of sulphide minerals or by direct oxidation of metals. Highly electropositive metals, such as A1 and Mg, occur only as oxides rather than as sulphides. Some important oxide minerals are haematite (Fe203), magnetite (Fe304), bauxite (Al203. 2H20), cassiterite (SnO2), cuprite (Cu2O), zincite (ZnO), rutile (TiO2). pyrolusite (MnO2), chromite (FeO,Cr203), uraninite or pitchblende (2U03.U02), etc.
