The Six Main Steps of Iron Ore Processing | Multotec Canada

The concentrate collected from the middlings and tails after spiral gravity separation has a lower iron concentration (magnetite) so it must be further concentrated to achieve the customer’s 65% Fe concentration. It is immediately directed to a magnetic separator circuit. Magnetized drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The,Modeling and Optimisation of Spiral Concentrator for,,Spiral concentrators are widely used in the iron ore industries to concentrate heavy iron oxides from light silica gangue minerals. The operation of a WW-6 spiral for the concentration of an iron,Spiral Concentrator | Multotec,Multotec-designed spiral concentrators are used across the world in coal, gold, iron ore, mineral sands, platinum and chrome processing plants and other minerals..

IOC’s nominal concentrate production capacity is,Iron ore - Wikipedia,Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, at high temperatures. Thus, the iron ore must be powdered and mixed with coke, to be bu…
