B.C. researchers develop new coal ‘washing’ process - JWN ...
Aug 17, 2020 Metallurgical coal is still black after it’s been washed, but it is considered “cleaner” because the washing removes ash and certain minerals. The washing is needed in order to test the coal for its quality. But the conventional cleaning methods use toxic chemicals that are carcinogenic.
