Appendix E Coal Mining and Processing Methods Coal

Base Price/ Washing Charges shall mean the washing charges per tonne of raw coal (dry) processed excluding taxes duties. Beneficiation/ Washing shall mean improvement created by scientific treatment (through wet processes) on coal without destruction of its physical identity for the desired end use. Sulfur in coal exists in inorganic and organic forms, the former being mostly pyritic sulfur. Total sulfur contents in major coalfields are in the range of roughly 0.510 wt%. In coal combustion, to generate electric power and process heat, the sulfur is emitted as SO2, which is seen as one of the main causes of acid rain. This effect has led ...

Coal washing process

Feb 28, 2020 However, coal mining and its use in energy applications have resulted in considerable ecological issues. Coal washing wastewater is the tailwater of wet coal washing in coal processing, which contains large amounts of silt and slime with a typical characteristic of dark black color (Kirk et al. 2003 Yan et al. 2012). A process for demineralizing coal includes the steps of forming a slurry of coal particles in an alkali solution, the slurry containing 10-30% by weight coal, maintaining the slurry at a temperature of 150-250 C. under a pressure sufficient to prevent boiling, separating the slurry into an alkalized coal and a spent alkali leachant, forming an acidified slurry of the alkalized coal, the ...
