Applications It has been used in to enrichment the particle size 0.3-0.02 millimeters fine grain like iron, tin, chromite, ilmenite, tungsten, zinc, tantalum-niobium, gold, coal, monazite, rutile, zircon and other low-grade ores. The non-metallic minerals which have a big enough specific gravity difference. Features 1. Reasonable structure and small occupation area 2. High recovery, high efficiency, and precise separation 3. Non-required power 4. Light in weight, anti corrosion, rust and wear resistant 5. Simple installation and minimal maintenance requirements 6. Low operating cost and long working life 7. Reliable running with minimal operator attention 8. Strong adaptability to fluctuation of feeding amount, density, size and grade 9. The surface of corundum forms strong friction the concentration effect surpass plastic surface
