### Iron ore - Wikipedia

Lower-grade 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, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

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

### Gravity Concentration | Gekko

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.
