Gold Ore Processing Basic Steps. 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.
During operation, the high-speed rotating impeller scatters and crushes the material, which then collides and grinds together before discharge. There are two crushing methods: rock-on-rock and rock-on-iron. Roll Crusher. Roll crushers crush materials through the compression action of two rotating rollers. They are commonly used as tertiary ...

Quartz is classically aligned with gold.The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz. It's universally considered the richest of the gold ores out there.
