Mineral Spiral Chute for Mining Sand Separation and Sand Recovery
Product Description
Mineral spiral chute for mining sand separation and sand recovery
Spiral gravity separator spiral chute is also called spiral concentrator or gravity separator, it's a kind of gravity concentrator which can separate mineral particles according to density, granularity and shape by the interaction of centrifugal force, friction force of chute surface, water flow pressure and gravity of minerals. Spirals are made of high-density fiberglass, high quality emery and unsaturated resin.
The spiral chute is suitable for separation of 0.3-0.02mm fine materials such as iron ore, ilmenite ore, chromite ore, pyrite ore, zircon ore, rutile ore, monazite ore, tungsten ore, tin ore, tantalum ore, niobium ore and other materials with enough specific gravity difference. It is the best roughing gravity equipment, which has been widely used in ferrous and nonferrous metal mines.
>>> Spiral Chute Application:
Spiral chute concentrator is widely used to the separation for mineral particles, the size of which ranges from 0.3 to 0.02 mm. it can be suitable for dealing with different kinds of ores, such as below:
-Rutile, ilmenite and zircon concentration.
- Iron ore, chromite and manganese beneficiation.
-Tin, tantalum and ore concentration.
-Gold, native copper and base metal recovery.
-Silica sands processing.
-Titano-magnetite concentration.

>>> Spiral chute working principle
Ore pulps are uniformly fed into machine and form different layers as they pass across chute. Heavy minerals precipitate to bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner due to the speedy rotation. As a result, mineral particles with different density are divided into three zones------concentrate, middling and tailing.
>>> Gold processing plant
Placer gold ore with high gold content mostly exists in the form of particles. Therefore, the ideal method to process placer gold ore is gravity separation.
