Abstract
Solid particles comprising combustible matter (e.g. coal) associated with or contaminated by inert matter (e.g. ash, rock) is segregated in a segregation zone into low density/small size and high density/large size fractions. The low density/small size fractions are passed to a utilization zone for conversion of the combustible matter. The high density/large size fractions are size reduced (e.g. by grinding) and either returned to the segregation zone, or passed at least in part, directly to the utilization zone. The conversion of the combustion matter proceeds more efficiently as a result. The segregation zone may operate by fluidized size/density segregation and in the utilization zone, the combustible matter may be at least partially combusted, preferably in a fluidized bed.
