Gravity separation is a important mineral recovery method and has been the main beneficiation sector used in gold mining plants, alternatively ahead of other processes such as flotation and cyanidation. Gravity separation is an environmentally friendly beneficiation method that relies on water flow and gravity to separate target value minerals and gangues.
Automatic Discharge type Centrifugal ConcentratorCentrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped concentrate bowl, rotated at high speed by ...
Dec 17, 2020· Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse (>20 mm) ores; spiral chutes, shakers and centrifugal concentrators for ...
