The ore dressing technology of chrome ore mainly has Gravity separation process, the chrome ore mining equipment are jig separator, shaking table, spiral classifier, centrifugal concentrator and spiral chute, and sometimes the concentrate will be selected by weak magnetic separator or high intensity magnetic separator to further improve the grade of chromium concentrate and the ratio of chromium iron.
The Spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity 0.3 0.02 millimeters fine grain like iron, tin, tungsten, tantalum niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non metallic minerals which have a big enough specific gravity difference.
Chrome Ore Mining Process: First use hopper and vibration screen feeding stone chrome to preliminary crusher, then to fine crusher, Then use belt conveyor to a hopper, underside the hopper has a feeder, feeder 0 20mm size to ball mill, ball mill working together with spiral classifier, then get 0 1mm size to shaking table, shaking table also have two stages, one for preliminary, one for fine.
Study on Knelson Concentrator Gravity Separation of a Polymetallic Ore Bearing Gold The major methods of recovering gold are gravity separation, gold flotation, cyanide. In fact, traditional gravity separators, such as jig machine, spiral chute, gold shaker table, have the shortages of low beneficiation ratio and low productivity.
