This applies to sorting size 0.3 - 0.02 mm thin materials of iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, P B ore, tungsten ore, tin mine, tantalum and niobium mine, as well as other non-ferrous metals.precious metals and non-metallic mineral with the proportion differences.The process of sorting equipment is stable, easy to control, to allow changes in the thickness of ore concentration, concentration is high, high recovery, small footprint, less water consumption, simple structure, no driving force,big capacity, simple to install, convenient operation, small investment and so on advantages.
