ABSTRACT:
A process particularly suited for producing anthracite coal having an ash content greater than about 20 percent. In the process, an aqueous feedstock slurry composed of raw input and a heavy medium having a magnetic component is subjected to a particular type of cyclonic separating action which produces a coal product having a specific gravity of at least about 1.9 while the specific gravity of the heavy medium is maintained at least about 0.4 units below the specific gravity of the coal product. The configuration of the cyclones and composition of heavy medium is such as to enable separation to occur at a relatively high specific gravity with a medium of relatively low specific gravity and viscosity, thereby minimizing magnetite ore losses and energy required to effect separation.
