The study presents an innovative approach for iron ore microfines (-150 microns) utilization in sintermaking as micropellets (2-6 mm). Sinter mix comprising of 60-80% iron ore microfines, 20-40% sinter grade iron ore fines (-8 mm), fluxes and coke fines (-1 mm) as coating layer on sinter granules were subjected to pot sinter experiments. Sinter bed permeability improved due to uniform spherical-shaped micropellets in sinter mix. The sinter indices including product yield and tumbler index were measured. The paper deals with the effect of different proportion of microfines and process parameters on sinter quality and productivity.
