ELI5: What is clean coal? : explainlikeimfive
"Clean Coal" is a term for using technological means to reduce the polluting potential of coal. This can be through preprocessing the coal to remove some of the toxins prior to burning. In this case the coal is "scrubbed" by subjecting it to steam and heat.

Health impacts of domestic coal use in China PNAS
Domestic coal combustion also has caused selenium poisoning and possibly mercury poisoning. Better knowledge of coal quality parameters may help to reduce some of these health problems. For example, information on concentrations and distributions of potentially toxic elements in coal may help delineate areas of a coal deposit to be avoided.
