Grinding for Liberation and Flotation

The question of why are we grinding to some target grind, how efficient should that grinding be, do we care if we generate excessive 10 um particles, is not being asked. For a flotation process have we really understood the whole liberation versus recovery, and optimization between primary and regrind.

Grinding Optimization Spotlight | Intellisense News

The Grinding Circuit Optimization Challenge. The operation and performance of Grinding Mills, especially SAG Mills, are significantly influenced by the density of the mill charge. The decision of what feed dilution ratio to target on its feed or how much water to feed into the mill compared to the solids feed is critically important.

Optimizing Grinding and Regrinding Capacity in Mill Design

Optimizing Regrinding Capacity. The justification, for including regrinding of a concentrate or middling in the design of any new copper flotation plant, should be that a greater economic return (by any preferred, economic criterion) will result thereby than is obtainable at any fineness of primary grind, without regrinding.
