Mechanochemical solvent-free reactions by milling, grinding or other types of mechanical action have emerged as a viable alternative to solution chemistry. Mechanochemistry offers not only a possibility to eliminate the need for bulk solvent use, and reduce the generation of waste, but it also unloc …

This paper reviews the experimental studies examining the interactions between grinding media, gold bearing pyrites and process water occurring during grinding of refractory gold ores and the effect of these interactions on flotation response of pyrite. The literature review reveals that the interactions are highly convoluted.
