What is iron ore pellet. Iron ore pellets are made by adding a small amount of additives to the fine ore powder (-200 mesh, that is, the ore powder with a particle size of less than 0.074mm accounts for more than 80%, and the specific surface area is more than 1500cm2/g), adding water to the pelletizer, relying on capillary force and mechanical …

The capacity increased from 20.70 in 2010 to 37.4 Mt/year. This has been necessitated by a drop in iron ore production through bans on production as a result of illegal mining detected in iron ore-producing states like Karnataka and Goa and imposed caps on production on well-known iron ore-producing belts of Orissa.

Whether referring to naturally iron-rich DSO fines or lump or artificially enriched beneficiated concentrate, one of the key elements that determines value is its chemical composition, or 'grade'. As a rule of thumb, a higher iron content will generally mean a higher market value for the ore since iron units are what a steel mill wants.

The pellets that are out of the balling drums are delivered to the roller feeder to remove the fines. The correctly sized pellets are hardened by preheating to temperatures of 1200-1300°C in a rotary kiln. After the heat treatment, iron ore transforms into hard pellets that are fit for transportation. Sources and Further Reading
