Abstract :

 This paper reports the demineralization of coal with EDTA, citric acid, ammonium acetate acid mixture, HCl, and HNO3. The residual coal were water washed and filtrates were evaporated to constant a volume. The residual coals were ashed and mixed with acid mixture followed by two hours of digestion. The filtrate were stored in glass bottles. The absence of some morphological features correspond to inorganic elements in residual samples confirms demineralization. It is evident from the results that amongst the leachants used; acid mixture and EDTA have caused significant reduction in ashes.
