Résumé : Since August 1984, Ciments Portland Liegeois SA and the Laboratory for Ore and Coal Preparation of the ULB have been collaborating in a research on the recovery by froth flotation of waste heap coal. This research has shown that certain tertiary amines are far more efficient oxidized coal collectors than the reaction agents proposed up to the present.
