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 association, and the specific gravity of the separation.

Coal Beneficiation Technology. So far in this module we've looked at how coal or minerals are In this we focus on the beneficiation of coal, in the next topic we will look at the processing of This is so as to reduce transport cost, why pay freight cost or worthless rock, and increase the calorific value.

As India’s coal is high in ash content, coal beneficiation should be done to reduce the ash content and improve its grade. Note: Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both.
