An improved coal deashing process wherein soluble dissolved coal present in the ash concentrate product stream from a critical solvent deashing process can be separated and recovered from the ash concentrate by at least two alternate processing systems.In one such system, the ash concentrate (containing dissolved and undissolved coal) is admixed with a suitable organic solubilizing solvent to obtain partial redissolution, at elevated temperature and at pressures of atmospheric and above, and thereafter subjecting said mixture to a separation treatment. The liquid product thus separated, containing substantially all of the dissolved coal and only a minor amount of mineral ash, thereafter is recycled to the initial coal dissolution step to thereby provide a portion of the initial solvent necessary for preparation of the coal feed.In the alternate process, the ash concentrate (containing dissolved and undissolved coal) is again partially redissolved by admixing with a suitable organic solubilizing solvent, at elevated temperature and at pressures of atmospheric and above, and thereafter subjecting said mixture to exact and precise separation treatment. Said separation treatment being designed to effect a clean separation of coal liquefaction products from solids to thereby produce, after removal of the solvent, a deashed coal product having a low sulfur content and less than 0.15 weight percent of mineral ash.
