Gravity methods use the difference in the density of minerals as the concentrating agent. Sometimes gravity separation is employed prior to flotation; this results in a concentrate containing up to 50 percent platinum metals, making smelting unnecessary ...

CONCENTRATION | GRAVITY SEPARATION - FUNDAMENTAL …

Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.

1. HaematiteGravity separation technique is used where iron ore (hematite) bearing minerals are free from associated gangue materials. The specific gravity of iron - bearing minerals is usually higher than the specific gravity of gangue materials. Effectiveness efficiency of the gravity separation depends largely on proper crushing and sizing of the ore so as to ensure a proper size feed to ...

Gravity concentration | Britannica

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.
