ABSTRACT:
A method of and an apparatus for the treatment of mineral coal containing pyrite wherein the mined mineral product is milled, classified into a fine component and a coarse component, the coarse component is recycled and the coarse component in whole and in part is subjected to density suspension so that a light product consisting predominantly of coal is separated from a heavy product comprising the pyrite and mineral detritus. This latter product forms a combustible mixture which is subjected to fluidized bed combustion in the presence of lime to produce an exhaust gas which is used to fluidize the vibrating trough serving as the density separator and as the drying gas and entrainment gas for the mill. The solid residue consists of gypsum (calcium sulfate) and ash and can be used, e.g. in the mixture of cement or plastic, but in any event does not pose an environmental hazard.
