### Grind Size Liberation for Optimum Flotation Recovery

Here is a trick for knowing if your flotation feed grind size is fine enough to achieve adequate mineral liberation without doing a full mineralogy study If your key mineral is sufficiently liberated, it should float and be recovered in the first few minutes in an initial %mass Increasing the grind size for effective liberation and Flotation testing indicated that an increase in copper recovery of approximately 1% could be achieved, or that a grind size increase of approximately 30 μm may potentially yield equivalent copper recovery due to the microwaveenhanced liberation liberation size flotation gkijnlHighlights Rate data for flotation of fully liberated and composite galena particles has been reinterpreted Rate constants of all particles show similar behaviour with respect to particle size For a given fractional liberation, reduced rate constant k/k max is independent of particle size A liberation function is defined, which is The effect of surface liberation and particle size on

### Froth flotation Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents34 Data per sizeliberation classes 341 Distribution of size liberation classes in feed and definition of variables Once there are two levels of distributions (size and liberation) under global results, data can be presented in several ways, depending on the basis used to determine the distributionsModelling flotation per size liberation class – Part 2 Grind Size Liberation for Optimum Flotation Recovery Selective flotation is allowed by a minimum liberation level in which you maximize metal recovery in a minimum mass Recognizing the partners can save you much needless pain Now I do not advocate unnecessary grinding, but grind size liberation for optimum flotation recovery
