Green Pellet
The ore being pelletized must have a sufficiently fine particle size distribution. Sufficient moisture needs to be added to make the ore sticky enough to pelletize, but not so much moisture that the ore becomes "muddy." A binder is required to hold the particle grains together before, when, and after the pellet is dried.
