The studies on hydrocyclone and magnetic separation had indied that an iron concentrate of 61 65 per cent Fe could be obtained by recovering 59 78 per cent of the iron values present in the slimes. Depending on the nature of the slimes the alumina and silica levels have been brought down to and per cent respectively.
Hydrocyclone . Hydrocyclones also find appliion in the separation of liquids of different densities. A different description: A hydrocyclone is a mechanical device designed to reduce or increase the concentration of a dispersed phase, solid, liquid or gas of different density, by means of centripetal forces or centrifugal forces within a vortex.
