Further removal of ash and sulfur from fine coal can be accomplished by flotation. Preliminary tests carried out, involving kerosene as collector and MIBC as frother and using laboratory Denver flotation cell, showed that 25–40 percent sulfur rejection and 30–50 percent ash removal can be reached, for a coal loss of about 20 percent. A higher level of mineral matter rejection is possible ...
