Conventional and recent advances in gravity separation
网页2023年2月1日 Conventional gravity separation is ineffective in separating fine (<0.1 mm) coal and gangue minerals (Fig. 5) because the settling velocity difference under a normal gravitational field of 1G is small. Rather than gravity separation, surface-based
