Gravity Concentrators. Of available treatment options, gravity concentration is by far the oldest method of physical separation. Capitalizing on differences in the specific gravity of minerals, liberated valuable ore materials are concentrated i.e. collected into very small, high-grade masses.
Examples of beneficiation processes include froth flotation and gravity separation. Other economic uses of the term are in use. For example, in the diamond industry, the beneficiation imperative argues that cutting and polishing (processes within the diamond value chain) should be conducted in-country to maximise the local economic contribution.
Ore and coal beneficiation method - ABADI; KHODABANDEH. Ore and coal beneficiation method. United States Patent 4702824.In one of its more specific aspects, it relates to a method of enhancing the removal of pyrites, especially iron pyrite, from a mineral or coal containing pyrites, by froth flotation.
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.
