Beneficiation Of Coal Fines In South Africa

Dense-medium beneficiation of fine (minus 0.5 mm) coal is not a new concept and has been used in South Africa previously. The dense-medium fine coal plant at Greenside Colliery operated for almost 18 years and, despite proving a difficult plant to operate, did succeed in producing a fine coal product with a low ash content of 7%. No other beneficiation

    Developments in Fine Coal Beneficiation in South Africa

    Fine coal cleaning has come a long way in South Africa in the past decade, as evidenced by the installation of 5 Mtpa of spiral plant capacity, the re-appraisal of froth notation technology resulting in major modifications to most operating flotation plants, and vigorous research into column flotation and oil agglomeration. This paper reviews the developments which have been made, and the
