Mineral Beneficiation and Processing of Coal, clean coal at the coarsest possible size. Conventional gravity separators, such as Jigs and dense media cyclones, are very common for treating coarse particles. Whereas, processing of fine particles could be achieved following advanced gravity concentrators and froth flotation techniques. Processin

Application of Biotechnological Approach for Making Coal an Environmentally Friendly Fuel,or heterotroph for organic sulphur removal. Several biological studies have been performed reporting about 50–80% of pyritic sulphur removal and 46–90% of organic sulphur removal. However, the biological process being a slow process needs to be considered for further improvements, viz., improvement

Preparation of Coal-Derived Activated Carbon and Its Application for Adsorption of Metals from Aque adsorption of metal ions in such aqueous solutions. Perspectives were also discussed with pertinent issues in the preparation of coal-derived activated carbon as the guideline for future works. Using coals as the activated carbon precursor could be part of contributors towards clean coal technology
