Dry beneficiation of iron ore
On account of the low process costs, DSO ores with iron content of 58 % are produced. For magnetite ores, beneficiation is typically more complex with finer ore grinding and downstream DMS (Dense Media Separation) and LIMS (Low-Intensity Magnetic Separation) separation processes. For DMS and LIMS, various technologies are used.
