Mineral processing Wikipedia
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.
gravity separation of iron ore pdf
1) Gravity separation The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately 2.7t/m3). Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities.

Separation Behaviour of Iron Ore Fines in Kelsey
The major advantage of enhanced gravity separation is its ability to reject composite particles more efficiently than flotation [4]. Among the enhanced gravity separa-tors, the KCJ is very promising due to its higher produc-tion capacities and utilization of less plant area. The KCJ is successfully demonstrated for the concentration of tin, mineral sand, gold, platinum ores and iron ore slime

Gravity separation Wikipedia
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
