The 325 mesh sieve size (45 microns) was selected because of experience with iron pelletization. When pelletizing iron ore, the feeds generally average 65% minus 325 mesh. At that product size, the Blaine test surface areas vary between 1,100 and 2,500 square centimeters per gram (cm 2 /g), a range that is ideal for pelletizing.

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.
