Mneral processing of iron ores

The efficiency of reduction-roasting/magnetic separation of hematite, goethite and any extremely finegrained iron ore, which is non-responsive to conventional processing techniques, is reviewed. Roasting equipment, roasting mechanism, superior results over conventional techniques, and certain advantages are highlighted

    Jun 21, 2018 Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process

    Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used
