Gravity separation by falcon concentrator- an over review
Gravity separation is appropriate because the density of graphite differs from that of LiCoO 2, and conventional equipment cannot perform efficient separation due to the decreased settling velocity of particles. The Enhanced Gravity Separators (EGS), on the other hand, increased the separation accuracy of fine fractions.

Gravity Spiral Concentrator Working Principle
The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4) Optimum Operating Conditions of ... Gravity Spiral …

SEPARATION TECHNIQUES
SEPARATION TECHNIQUES. If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue)
