cyclones. Furthermore, the slurry mixture of the heavy medium utilised for the purpose of dense medium separation should be non-detrimental to the effectiveness of separation in the DMS Fine cyclone plant. Medium characterisation showed that removal of ultra-fines leads to unstable media as indicated by faster settling rates.

The Sishen iron-ore-mine produces 3 pro= ducts with size gradings of 25 to 8 mm, 11 to 5 mm and 5 to 0,2 mm and has a product capacity of 20 Mtpa. Ore is produced at an average Fe content of 66,2 % Fe for the two coarser pro= ducts and an average of 65,3 % Fe for the fine ore product. Three stage crushing is practised to re= duce the run-of-mine ore to -90 mm after …

Heavy media separation dates back to several centuries Initially, a fine magnetite was used as a heavy media In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore The heavy media ...
The ore particles of +6 − 100 mm in size are treated by the wet dense medium separation, for which the density of the dense liquid is adjusted at 2750–3150 kg/m 3. Although development of dry separations for iron ore is strongly needed, the dry dense medium separation has not been tested for iron ore.
