12/10/2018 Gravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (e.g. air, water) etc. Hence, besides gravity, other factors, such as size, shape etc.,

15/04/2017 Chromite ores contain a variety of gangue minerals such as serpentines and olivine. Therefore, some kind of concentration is required for beneficiation of chromites. The most commonly used beneficiation methods for chromite ores are the gravity methods, such as shaking table, jig, spiral, and Reichert cone. Magnetic separation is also used depending on the ore characteristics. Flotation is also used for the beneficiation of finely grained ores.
