Chute gold separation The main equipment for chute gold separation is a spiral chute, which uses inclined water flow for separation. Under the action of combined forces such as water flow, mineral gravity, and friction between ore particles and the bottom of the chute, the ore particles will settle in different areas in the chute according to specific gravity.
