Concentration of ore is the process used to extract useful minerals by separating the gangue particles. Concentration of ore can be done by 4 methods: Hydraulic Washing, Magnetic Separation, Froth Floatation, Leaching. Hydraulic washing depends upon the weights of the metal and gangue particles.

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 of gold.

The gravity separator separates products of same size but with difference in specific weight. It has a vibrating rectangular deck, which makes it easy for the product to tr kiavel a longer distance, ensuring improved quality of the end product. The pressurized air in the deck enables the material to split according to its specific weight.

3.2 Gravity separation process The density of chromite ore is slightly higher than that of its other magnetic gangue ore. Therefore, the separation of ferrochromium from other minerals can be realized by gravity separation. Use spiral chute to separate the concentrate process tailings and the scavenging process concentrate respectively.

Big Chemical Encyclopedia Gravity separation process 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.
