In the early developmental stages of iron ore beneficiation, relatively coarse grinding was used and the Blaines of the concentrates usually ranged from 1300 to 1600 cm²/gram. Although drum filters were briefly used for early dewatering in order to compete with direct shipping ores, capital operating costs were reduced by employing the disc ...
A current trend amongst producers is the increase in dewatering of iron ore fines (0.5 mm), due to an increase in wet beneficiation processes used to upgrade lower quality ore deposits, increased water content in orebodies located below the water table, and …
