Gravity Separation Equipment Alternatives for Fine Coal

Gravity Separation Equipment Alternatives for Fine Coal

Surface-based separation processes such as froth flotation and oil agglomeration have been traditionally recognized as the only practical methods for cleaning fine coal i.e. 100 mesh x 0. These processes are very selective in rejecting well-liberated mineral matter, but are much less effective if the feed coal contains a disproportionate ...
