    The effect of thermal drying on the mechanical strength of South African coal December 2008 ; Journal of the Southern African Institute of Mining and Metallurgy 108(12) Authors: M Le Roux Northcoal, thermal drying also has an effect on the coal’s mechanical strength (from here referred to as strength)2 The strength of coal is an important property since it has a direct effect on the particle size of the coal The particle size of the final coal product can then in turn affect the productivity and efficiency of downstream processes such as gasification Studies have shown that theThe effect of thermal drying on the T mechanical strengthexists in the South African coal industry that thermal drying is impractical, unsafe and/or uneconomical The fine coal that is generated during the coal mining and processing operations has traditionally been pumped as slimes to codisposal discard dumps This fine coal constitutes about 10–15 per cent of annual run of mine tonnage2 Economically viable techniques to dewater the fine coalAn investigation into the moisture absorption properties

  • Potential uses of South African Coal Fines: A Review
