Mineral Spiral Concentrators | Multotec

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ...

Process Of Gravity Separation Of Iron Ore

Oct 12, 2018· 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 ...
