Enhancement of magnetic separability in coal

The conversion of coal to a clean fuel through liquefaction requires the physical separation of undissolved sulfur-rich mineral matter. The hydrogenation-liquefaction reaction produces residual solids in which the original coal impurity pyrite, FeS 2 , has largely been converted to pyrrhotite, Fe 1-x S, which is a complex non-stoichiometric sulfide.
