Mill scale is a steelmaking by-product from the rolling mill in the steel hot rolling process. Mill scale contains both iron in elemental form and three types of iron oxides: wustite (FeO), hematite (α-Fe 2 O 3) and magnetite …

view more201511 · Abstract Iron ore is primarily found as the oxides of iron, notably hematite and magnetite and as hydroxides like goethite and limonite. Small amounts are found as the carbonates in siderite, as sulphides in pyrites and as silicates in chamosite and greenalite. Indian economy is growing steel demand and supply will grow in the same way. As good …
