· The purpose of a gold mill, at least a simple one, is to crush and grind rock fine enough to release small particles of gold. After liberating the gold from the rock or gangue, it is then run through a gravity separation step, which will concentrate most of the gold and wash off the lighter waste rock. Step 1.
