IMPROVING FINES RECOVERY BY GRINDING FINER
N.W.Johnson – Mineral Processing Chair, University Of Queensland ABSTRACT "Conventional wisdom" has deemed that fine particles have low flotation recoveries. Plant size -recovery graphs often have the classic "hill" shape - high recovery in the mid sizes and low recovery at the fine and coarse ends. Yet if mineral liberation is poor, low
Influence of Fine Mud on Flotation Process And Solution
The primary fine mud is the fine mud formed by the natural weathering of minerals in the deposit, such as fine mud as kaolin and clay. Secondary fine mud refers to the fine mud produced in the process of mining, handling, crushing and grinding. Generally, the primary fine mud is more difficult to float than the secondary fine mud.
