The iron and steel industries in India are vitally concerned with agglomeration of iron ore fines. Indian iron ores are relatively soft and friable; during mining and sizing processes around 30-40% fines (particles below 8 mm size) are generated. The ore washing plants also generate around 5 million tonnes of slimes per year.
In the present investigation, the reduction and swelling behaviours (in low grade coal) of fired iron ore pellets, prepared by blending hematite iron ore fines of − 100, −18 + 25 and −10 ...
Iron Ore Pelletization: Part I. Fundamentals. ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding ...
