Iron ore pellets are commonly used as iron burden materials in blast furnaces. The pellets are small and hard iron ore balls. Their diameter is usually 1016 mm. The pellets are hotbonded in order to provide sufficient mechanical strength. A high iron content and a low gangue content is favourable for blast furnace pellets . Additives are ...

Another example has been presented by RioTinto, where the silica content in DR pellets was decreased from to under 1% through the implementation of silica flotation (Chaigneau 2015).However, the benefits of obtaining a higher iron content in the ore product must be weighed against the iron losses due to the separated gangue, the tailing grade and a property varying with the ore mineralogy.

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.
