Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.

Gravity separation is sufficient for production of good-quality steam at lower boiler operating pressures (e.g., 150 lb/in. 2), where the steam and water density differential is great and the steam drum is adequate for the steam load.. Anti agents can significantly reduce carryover caused by chemical factors. Compounds classified as polyalcohols and polyamides are particularly effective in ...

Gravity separation occurs primarily due to weight and size differences between different particles. The size of the particles is an important parameter as a large grain of a gangue mineral (e.g., quartz) behaves like a small grain of gold in a classic gravity separation process.

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 …

The angular velocity (ω) is often expressed in terms of the rotational speed, N. w = 2πN/60 where w = 60νr/2πr. The centrifugal force, F c, is given by: Fc = mf (2πN/60)2 = 0.01097 mrN2. Centrifugal force is often expressed in the magnitude of the force with respect to the gravitation force (g's):
