Grinding effect on kaolinite-pyrophyllite-illite natural
The effect of dry grinding (mechanochemical activation) on a natural mixture of aluminium silicates composed of kaolinite pyrophyllite and potassium mica (illite) was studied. The evolution of the ground material was followed by X-ray diffraction differential thermal analysis thermogravimetric analysis scanning electron microscopy and nitrogen adsorption methods.

Effect of Grinding Environment on Galena Flotation
· The effect of grinding media type after 60 min grinding on the flotation recovery of galena was investigated. Table 1 shows the effect of grinding media type on galena recovery. It can be seen that the galena wet-ground with mild steel media has a lower galena recovery than galena wet-ground with stainless steel media.

· Different from pyrophyllite the OGM has little effect on pyrite flotation and the recovery of pyrite changed relatively little. The flotation recovery of pyrite and pyrophyllite were about 87 and 20 respectively when the OGM dosage was 50 mg/L indicating that the flotation separation of pyrite from pyrophyllite can be realized at an OGM dosage of 50 mg/L.
