Ultrafine Grinding - an overview | ScienceDirect Topics

Ultra-fine grinding (P 80 ≤ 10 μm) has been proposed as an alternative to “unlock” gold from sulfidic refractory ores; however, the cost of size reduction to this level makes it applicable only for concentrates (Corrans and Angove

Mill (grinding) - Wikipedia

SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles.
