In addition, the E value is 0.14–0.145 g/cm 3 for −6 + 1 mm coal separation using the air table separator. The separation ...
Multi-gravity separator: an alternate gravity concentrator to process
The multi-gravity separator (MGS) is a novel piece of equipment for the separation of fine and ultra-fine minerals. However, the published literature does not demonstrate its use in the separation of coal fines. Therefore, an attempt was made to study the effects of different process variables on the performance of an MGS for the …
