Coal beneficiation technology to reduce hazardous

Coal beneficiation is a process to remove mineral matters and sulfide minerals from the coal to meet the market criteria such as ash, moisture, sulfur, and heat content (Noble and Luttrell, 2015, Miller, 2017), and coal with a higher heating value is obtained after the beneficiation as the ash and sulfide-bearing minerals are removed from the coal.
