(PDF) An analysis of medium losses in coal washing

Adjustments of the level of magnetite water increases the magnetite losses. An increase in the per- slurry in dilute medium sump could help increase rel- centage of solids in the feed and the percentage of coal in ative density of feed to the primary magnetic separators. feed also increases the magnetite losses.
