The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. most gold ores, however, only require separation into two partsthe concentrates, in which the precious metal is ...
Generally, when the quotient is greater than (whether positive or negative), then gravity separation is relatively easy. With a decrease in the value of the quotient the efficiency of the separation decreases and below , gravity concentration is not feasible. P1007 74
Gravity Separation or Hydraulic Washing (Levigation) This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them.
Ore Gravity Concentration India. gravity seperation of ores india Mineral processing Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation …

Gravity concentration. Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as ...
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 ...

Fig 1 Effect of centrifugal force on gravity force. Separation of the ore particle by gravity is dependent on two factors namely (i) settling rate of the particles, and (ii) difference in specific gravity when compared against the medium in which they are being separated, this gives differential settling rate and has been termed the ‘concentration criteria’.Settling rate of a particle is ...
Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
