Separation techniques mineral processing Flotation. Flotation is a gravity separation process which exploits differences in the surface properties of particles. Gas bubbles are generated in a liquid and become attached to solid particles or immiscible liquid droplets, causing the particles or droplets to rise to the surface. This is used to separate mixtures of solid-solid particles and liquid ...

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Magnetic Separation Highly magnetic minerals are removed from the dried heavy-mineral concentrate using a hand magnet. The heavy-mineral concentrate may then be passed through a Franz isodynamic magnetic separator. For the first pass, a longitudinal tilt of 20º, a transverse tilt of 10º, and a magnet current of 0.2 – 0.8 A are employed.
