Abstract

Arguments are given for dry or for wet separation of coarse coal and shale. An overview is given of dry treatment methods for run-of-mine coal used successfully, now and in the past. Examples are given of separators based on gravity force in combination with the material properties density, friction, and resiliency. Specific details are given of fluidised sand separators. Current improvement potential for the dry separation of coal is discussed. Results of experiments with a pilot size dry fl uidised sand separator are shown.
