Reduction of Sulfur and Ash from Tabas Coal by Froth Flotation

siderite, etc., sulfate and sulfides, etc., are the major ash-forming minerals in coal [1]. However, high sulfur coals can be upgraded by desulphurization through physical, chemical and bio-technological processes. Oneof the most suitable physico-chemical methods is froth flotation for removal of pyritic sulfur from coal [2].
