ABSTRACT:
Particular readily separable particulate sulphur-reactive scavenging materials are heated with sulphur containing particulate coal to extract sulphur from that coal. Reacted portions of the particulate scavenging material are then separated from the particles of coal, using a separating force effective on the scavenging material and which serves to also separate the reacted portions of the scavenging materials.
