Conventional coal cleaning process deals with coal practically in as-received state, in which mineral matters at micronized size embedded within organic matrix of separated particles could not be removed. Removal of such finely disseminated minerals by physical process requires ultra-fine coal grinding for mineral liberation, separation of ultra-fine particulate system and dewatering of ultra-fine coal products, which as a whole is a new phase of physical coal cleaning. Liberation followed by separation of valuable minerals is the conventional beneficiation process of most metallic ores. Applying the same in coal cleaning, peculiar technical problems should be solved in conjunction of economy to render it practical. This paper describes the development of such process, gives examples of coal cleaning performance and foresees its application.
