A model to assess the success of separation based on gangue
recovery and valuables recovery was taken and refined. Two new parameters have been described, one to evaluate the achieved liberation
and one to evaluate the achieved separation. These parameters
were generated on an equal mathematical basis which
enables a direct comparison between both process steps. A third
parameter was calculated based on the two newly introduced ones,
which could be used to assess a whole mineral processing chain
with regard to liberation and upgrading.
To show the applicability of the model
