Analysis: Australian thermal coal producers eye coal ...

Thirdly, when producing semi-soft coking coal from a wash plant, some coal volume is lost in the process -- up to 10% -- and this can impact profit margins, a source said. Australian coal producers incur a cost of about $3/mt from washing thermal coal which has the effect of reducing its ash content from 14% to around 9% or less, he added.

How Coal Works | Union of Concerned Scientists

Dec 15, 2017· If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.
