COARSE DRY COAL CLEANING
Dry Coal Cleaning Applications in India Many coals located <1000 km away from the utility are not cleaned. As a result, 40%-45% ash coals are transported and used in utilities designed for 25%-35% ash coal. For a relatively easy-to-clean India coal, dry cleaning has the ability to reduce the ash from 41% to 30%. 0 5 10 15 20 25 30 <1.35 1.35-1. ...

Coal prices and outlook
Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2021, the average delivered price of coking coal to coke producers was about $122 per short ton—about 3.3 times higher than the average price of coal delivered to the electric power sector.
