Grinding - Mineral Processing
2020-7-7 The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.

Over grinding - Metallurgist Mineral Processing
2021-6-14 You want to have at least 60% liberation of the ore. For gold this can be just a few microns so grinding to 80% 25micron is acceptable, given that operating costs increase with finer grinding. As always it’s a trade-off depending on ore size and gangue components.
