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. The partitioning of major, minor, and trace elements depends on the degree of liberation of the minerals, their inorganic versus organic ...
