iron hematite ore processing

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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCOTypes of Iron Ore Hematite vs. Magnetite INNJun 28, 2018· For that reason, hematite ore is important for many mining companies.As Australia’s Magnetite Network explains, “[d]irect shipping ores, when mined, typically have ironHematite A primary ore of iron and a pigment mineralUses of Hematite (Iron Ore) Hematite is the world’s
