Platinum concentrators in South Africa normally consist of two stages of grinding and flotation and this investigation was focussed on the second stage, where platinumcontaining particles tend to float slowly and the fine grinding leads to entrainment of chromite. Tests were performed on a lowgrade UG2 ore
Fig. 7 Interplay of grind time on particle size b) Coarse grinding affects flotation recovery due to low liberation and the decreasing ability of the bubbles to lift the coarse particle. DISCUSSION c) Increasing the recovery result in a reduction of the The graphical depictions comparing the flotation kinetics concentrate grade.
Effect of flotation reagents on the wet grinding of.

15/02/2005 · Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most sizereduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.
