Flotation of products from different grinding HPGR-rod mill systems showed that, on average, the flotation efficiency of sphalerite was higher in the dry system than for the wet method (Fig. 1). For PGMs, flotation of HPGR-rod wet ground products showed higher recovery than the dry process (Fig. 2). In the case of PGMs, slimes coating the ...

The impact of grinding environment on flotation has been investigated for different ores. In the flotation of platinum-group minerals (PGMs) from the Overysel ore (Bushveld complex in South Africa), dry grinding produced more fine particles, led to a higher degree of liberation for the PGMs but lower recoveries than wet grinding [11].
