Gold Ore
6. Epithermal gold ore. Epithermal gold ore is a type of gold ore that is formed near the surface of the Earth by the action of hot fluids. It is often associated with volcanic rocks or geothermal systems. The processing of epithermal gold ore involves crushing the ore to a fine powder, which is then mixed with water to form a slurry.
