Modeling and Optimisation of Spiral Concentrator for …

It is estimated that 18–25% of tailings are being generated during the processing of iron ore. The major compositions of iron ore slime are hematite, goethite, quartz, alumina, mica and kaolin (Roy and Das 2008). The iron ore slime is discarded due to its particle size and chemical composition which are not suitable as feed to the blast furnace.
