Pelletizing Aids in Upgrading Low-Grade Nickel Laterites
In the case of nickel laterites, the ore is typically crushed and ground, then mixed with the chosen reductant and any other additives, and pelletized into pellets in the range of 10-15mm. As with other metallurgical applications, pelletizing may be carried out using either a rotary drum (balling drum) or disc pelletizer (balling disc).
