[0008] Pelletizing is the most recent agglomeration process and it was a result of the need to use fine concentrates of magnetite from certain iron ores. Iron ore pellets are produced by agglomeration of particles of less than 45 mm in size, forming pellets of from 8 to 16 mm, in disc or rotating drum. The material to be agglomerated must have ...

Pelletization and iron ore reduction are accompanied by great reduction in energy and carbon dioxide emission. Enhanced rate and degree of iron ore reduction are due to secondary reactions involving carbon dioxide and the volatiles. Pellets reduced at 1550 °C show carbon dissolution up to 4 wt %, high porosity, low sulphur and slag levels.
