Iron ore fines - Cargo Handbook - the world& 39;s largest

Description. Iron Ore fines Iron 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, deep purple, to rusty red. The iron itself is usually found in the form of magnetite Fe 3 O 4 , hematite Fe 2 O 3 , goethite FeO OH , limonite FeO OH .n H 2 O or siderite FeCO 3 .

Iron ore - Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
