<p>Apparatus for the beneficiation of coal is disclosed. The apparatus consists of sequential combination coal pulverization means, feeding means to move the pulverized coal to a surface treatment reaction zone including means for the introduction of chemical reactants to surface treat the coal, and means for introducing the surface treated coal to a water wash zone having means for admixing ingredients therein under high shear agitation. The resulting beneficiated coal is of low ash and mineral sulfur content and of enhanced BTU content which can be burned as a solid or combined with a fluid carrier such as fuel oil or water to produce highly desirable beneficiated coal mixtures or slurries which are readily transportable and cleanly burned.</p> |
