Gravity separation : ALS

ALS provides gravity separation, in combination with other techniques, to identify and optimise the process flowsheet for the target mineral. Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

Gravity Separation ScienceDirect

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. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the material being suspende

Gravity Separation an overview ScienceDirect Topics

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.

Gravity

Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are attracted to (or gravitate toward) one another.
