Processing of Complex Ores | ScienceDirect

A particle size of below 10 μm has been considered the critical size below which the flotability and selectivity deteriorate rapidly. Therefore during the processing of finely disseminated massive sulphide ores requiring grinding from 40 μm to as fine as 15 μm, most of the losses in the mineral values occur in the minus 10 μm size.
