Gravity concentration memberfiles eewebs

If the ore contains an appreciable amount of sulphide minerals then, if the primary grind is finer than about 300p~m, these should be removed by froth flotation prior to gravity concentration, as they reduce the performance of spirals, tables, etc. If the primary grind is too coarse for effective

Iron ore Wikipedia

Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, highquality fine ore powders, are known as fines. Magnetite

Gold Gravity Concentration Mineral Processing & Metallurgy

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Compliions are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products.
