Attrition Grinding Mill Design
The tests were made in the 10- inch-diameter grinder to determine the effect of "polishing" the mica with nylon pellets subsequent to comminution of the mica with minus 14- plus 28-mesh sand. For comparative purposes, attrition grinding tests also were made using nylon pellets without a preliminary sand grind.

of Platinum Group Minerals (PGMs)
In order to achieve this, comminution circuits usually consist of two or three stages of milling, in which the first stage is autogeneous, followed by ball milling. Further liberation is achieved in subsequent stages using ultra-fine grinding. Each comminution stage is followed by flotation in the so-called MF2 or MF3 circuits. While this staged
Reduction of Fragment Size from Mining to Mineral …
2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral …
