Coal Beneficiation - an overview ScienceDirect Topics. Joan S. Esterle, in Applied Coal Petrology, 2008 3.7.2 Mineral and Trace Element Partitioning. As noted, one of the fundamental reasons for coal beneficiation is the reduction of ash yield and deleterious minerals and elements with an inorganic affinity.

 · A large-laboratory scale physical/microbial process was demonstrated for the removal of pyritic sulfur from coal. The process took place in an aerated-trough slurry reactor with a total slurry volume of 150 L. The reactor was divided into six sections, each of which acted as a physical separator and a bioreactor. The process objective was to physically …
