ABSTRACT There is an urgent need for development of environmental friendly processes through which iron ore fines can be beneficiated and utilized effectively. For processing of low-grade iron ores, ground to finer size necessitates the use of centrifugal force. This is because the settling rate of the particles in centrifugal force is 500–600 times more than that …
