Sasol converts coal to liquid fuels In two steps Figure 1. First, the coal 1s burned with oxygen and steam under pressure to yield a gaseous mixture which 1s principally hydrogen, carbon monoxide, and methane.Raw algal lipids RALs and their derivatives fatty acid methyl esters FAMEs were investigated as biocollectors for the recovery of coal from ash-rich fine coal waste by froth flotation. Testing was done on fine coal discards from two South African sitesa high ash 50, high sulphur 5.7 sample and a lower ash 26, low sulphur 0.91 sample.An important conclusion is that South African coals are floatable, and flotation selectivity can be obtained, provided process parameters are controlled within a narrow range. A more in-depth study of the liberation characteristics of the coal and gangue and of the individual macerals is needed because only this will limit the final result.

    Jan 01, 1988 South African coals have a much higher ash content than European coals. Consequently, ash entrainment is often a problem in the flotation of South African coal, since it adversely affects the concentrate grade. It has thus been very difficult to produce a low ash metallurgical export coal by this process.Jan 01, 1988 South African coals have a much higher ash content than European coals.
