Coal Rejects are a by-product of the coal washing beneficiation process, in which after separation of beneficiated washed coal and middling, the rejects are left over as a portion of raw feed coal. These are generated from the coarse circuit of the coal washery process. No additional crushing or blending is required for its usage.

Chromium speciation is vital for the toxicity of products resulting from co-combustion of coal and biomass. Therefore, understanding of formation processes has been studied using a combination of X-ray absorption fine structure XAFS spectroscopy and thermodynamic equilibrium calculations. The influence of cofiring on Cr speciation is very dependent on the type of fuel. CrVI contents in the ...
