Iron Ore Pelletization Technology and its Environmental Impact .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.hematite iron ore pellet technology china,Iron ore - WikipediaIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite.
