Earlier work with iron ore and iron ore fine/slime indi-cates that beneficiation of iron ore and fine/slime containing very low iron and high alumina and silica is quite difficult. Also, it is equally difficult to know the characteristic proper-ties of the particles where most of the population is below 50 micron.

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 …

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation [2]. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.
