Classification of iron ores by laserinduced breakdown

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 FeOOH limonite FeOOHnH 2 O or siderite FeCO 3 In most ores including iron ore valuable minerals are usually intergrown with gangue minerals so the minerals need to be separated in order to be liberated This screening is an essential step prior to their separation into ore product and waste rock Secondary crushing and screening can result in further classification and grading of iron ore
