ALS provides gravity separation, in combination with other techniques, to identify and optimise the process flowsheet for the target mineral. Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

CHAPTER-7 GRAVITY CONCENTRATION OF IRON ORE

May 01, 1995· Gravity separation is one of the oldest mineral processing techniques yet, with modern developments, it is still to the fore. Gravity concentration is, essentially, "a method of separating particles of minerals of different specific gravities by reason of their differences in movement in response to the joint simultaneous actions upon them of gravity and one or more other forces" (Taggart ...

Process Description Gravity Separation: For the gravity separation of barite, the process of HOT Mining is crushing, screening and jigging. Then the high grade (over 80%) concentrate will be produced. Jig is the main equipment for the separation and purification of barite ore, which is energy saving, high efficiency, and environment protection.
