The mill grinding process is almost carried out in two consecutive stages: one is dry grinding (coarse grinding) and the other is wet grinding (fine grinding).
How does the iron ore beneficiation process work?Answer (1 of 2): At its basic level, iron ore beneficiation consists of the following steps: 1. Crush and grind to a sufficiently fine size that the iron oxide minerals are broken free of the gangue minerals like silica (Liberation) 2. Physically sort the mineral grains to produce a concentrate ...
