Chute beneficiation belongs to the slant flow sorting process. The slurry is supplied to a inclined groove or inclined surface with a certain inclination. Under the action of water flow, the ore group is loose and layered, and the upper layer of light minerals is quickly discharged outside the tank. The lower layer of heavy minerals is retained in the tank or discharged from the lower part at low speed. After access, concentrates and tailings are obtained.
Spiral chute is the best equipment for mining and beneficiation, especially for the sand mining of seashore, riverside, sand beach and creek. The product has the advantages of reasonable structure, simple installation, small area, easy operation, stable ore dressing, clear sub-mining, large amount of processing, high efficiency, high enrichment ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture resistance, rust resistance, corrosion resistance, strong adaptability to fluctuations in ore concentration, concentration, particle size and grade, and no noise.
