Gravity separation is the traditional method for mineral beneficiation and irreplaceable when process minerals such as tungsten, gold, iron, tin, chrome, tantalum, niobium, coal, barite, etc. Because of its advantages such as low running cost, environmental protection and special effects on some minerals, it is still very popular at present. There are different types of equipment for gravity ...
Surfacebased separation processes such as froth flotation and oil agglomeration have been traditionally recognized as the only practical methods for cleaning fine coal ( 100 mesh x 0). These processes are very selective in rejecting wellliberated mineral matter, but are much less effective if the feed coal contains a disproportionate amount of composite particles (, middlings).
