Grinding analysis of Indian coal using response

2016-6-27  The present work discusses a systematic approach to model grinding parameters of coal in a ball mill. A three level Box–Behnken design combined with response surface methodology using second order model was applied to the experiments done according to the model requirement. Three parameters ball charge (numbers 10–20), coal content (100–200 g) and the grinding time (4–8 min) were ...

Frontiers Effect of Grinding Media on Grinding

2020-6-17  Grinding media have significant influence on the flotation of chalcopyrite and pyrite. This effect is mainly related to the change in the surface properties of chalcopyrite and pyrite. This paper investigates the influence of steel ball and nano-ceramic ball grinding on the floatability of chalcopyrite and pyrite. Flotation results, as well-scanning electron microscopy (SEM), X-ray ...

A review of the effects of grinding media and

2016-8-1  The relative exposed surface of sulfide in ore to grinding media can strongly influence the redox conditions in the mill and subsequent flotation behaviour. In the refractory gold ores, solid solution Au can take on oxidation states of 0, +1 (Simmons et al., 1999) or even +3 (Arehart et al. (1993).
