Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a green pellet or ball which is then dried and hardened in a separate step usually by heating Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum

A blast furnace is a steel cylinder lined with refractory It operates continuously until the lining wears out which takes many years to occur The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF Molten iron is produced in a blast furnace by the following steps 1
