Mineral liberation degree becomes an essential parameter for mineral processing, such as flotation. The goal for this type of process is to obtain an optimized liberation degree for the MOI for each particle at the coarsest possible particle size (Bradshaw, 2014, Cropp et al., 2013, Runge et al., 2003, Trahar, 1981).

HOW TO: Froth depth change

To get the most out of your experiments, you should always try to record the froth depth not only in cm's, but as a % of the FEH. Conducting a test with a froth depth that is 2 cms would be completely different if that 2 cms represents 50% or 80% of the FEH. So start with the FEH and we can discuss what next if you would like more input.
