Beneficiation of an Indian non-coking coal by

08.06.2016  Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indian coals are characterized by high inter

CHEMICAL BENEFICIATION OF LOW GRADE COAL - A REVIEW

Physical beneficiation of coal is not very effective in separation of the finely dispersed minerals, whereas chemical beneficiation uses expensive reagents and leads to generation of large amount of wastewater which needs to be purified before discharge. Thus, a combined approach consisting of physical and chemical cleaning of coal appears to have a potential for.

In the composite beneficiation system of coking coal in India, usually three types of products are obtained – clean coal, middlings, and rejects. It is observed that the proportion of middlings is rising day by day on one hand, and on the other the yield of clean coal is decreasing in the washeries because superior grade raw coal is depleting gradually. This phenomenon results in short ...
