Gravity Separation - SGS

Gravity separation is the most well-proven and accepted technique of concentrating minerals and has been used as a primary form of mineral concentration for centuries. Due to its high efficiency and low cost, gravity separation is always the first consideration in any flowsheet development program and always features in any flowsheet where there is sufficient differences between the specific gravity of

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.

PRINCIPLES OF GRAVITY SEPARATION

Gravity separators use air as a standard rather than water. Since air is lighter than water, the relative difference between particles of differing weights is widened. For this reason, the gravity separator is a very sensitive machine and when operated correctly can produce a very precise separation. The Process of Stratification Air is used as the separating standard through the process of ...
