Coarse semi-liberated material is inherently present in the size distribution of the grinding mill output, and it is not floated by conventional mechanical cell flotation units. This allows coarse particle flotation (CPF) to typically recover an additional 3–6% of the mineral contained in the run of mine (ROM) mill feed of copper concentrator ...
