Coal Flotation : The Status and Outlook

Abstract

Coal is the principal source of energy for India and will continue to remain as at the onsat of the 21st century. But the avaluation of coal as the major domestic energy source for the next century depends among other factors on finding solution for technical problems associated with beneficiation of coal to convert it into an environ-mentally acceptable fuel. The msot affective technique for cleaning coal fines is froth flotation. but msot ofthe developments in the froth flotation tachnology is in the areas of metallic mineral flotation. Processing plant operators very often tend to over look the basic differences in characteristics of coal and metallic mineral as raw matrial for flotation treatment.
