Chemical Beneficiation of High-Ash Indian Noncoking
2019-8-7 Coal mined from the Talcher region of Odisha, India is known to be high-ash, surface-oxidized, and noncoking in nature. It is quite challenging to beneficiate such low-grade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix.

Review on chemical upgrading of coal: Production
2017-4-1 Chemical treatment processes have been demonstrated as the most effective techniques for removal of ash forming minerals from coal to produce coal with minimal or almost no ash. In general, the ash content of UCC is reported within the range of 0.15 to 0.6% either by treating bituminous coal with HF followed by HCl or HNO 3 .
