Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

Design of Comminution Circuit for Optimum Performance of the Gravity Separation Unit at Itakpe Iron Ore Processing Plant, Nigeria Ajaka, E.O., Akande, J.M., and Saliu, M. A. Department of Mining Engineering, Federal University of Technology, Akure (FUTA), Nigeria Abstract

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 plant is suitable for artisanal or small-scale miners to recover high-grade gold grains from the quartz veins or other raw ores. Mini gravity concentration plant has simple structure, is easy to operate and move, costs low but it can achieve satisfied recovery. FUNCTIONAL MODULES Comminution module

Gravity separation, relies on the difference in density of the mineral and the gangue. This technology can be applied to primary recovery, preconcentration, and final upgrading, as well as recycling and soil washing.Hazen's gravity concentration facilities are among the finest in the world.

During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...
