Pellet Process Uses and Exposures May 2010 The Iron

Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material) are known collectively as the burden.
