Abstract In a method of and assembly for sorting a granular two- or multi-component mixture, containing a number p of granular, polydisperse solid components to be sorted out the particles of which differ in density and/or shape and have at least partially overlapping particle size and settling rate (partic- ulate characteristics) distributions the mixture, in which the components are present sortable, is subjected to two dry classification steps in which different particulate charac- teristics of the particles are decisive. First, The feed mexure is dry classified in a first step, in particular by sieving or wind sifting, into a greater number of classes of a first particulate characteristic, (into screening classes or settling rate classes), which are sufficiently narrow with a view to the subsequent separation of the components to be sorted out and in which the fractions of the second particulate characteristic (the settling rate fractions or screening fractions) of the individual components are contained separately or consecutively or only slightly overlapping. Then the components are separated in a second step by subjecting each class obtained to further classifying, in series of successive classifications, in particular wind siftings or sievings, so as to obtain the sorted out components pure or enriched. The selection of the width of the classes in the first step must be made, in consideration of the desired and possible sorting by classify- ing in the second step, in which the second particulate char- acteristic of the particles is decisive, such that graduation of the cut-off limits of the classifying in the second step is made possible in a manner at which the two limits of the second particulate characteristic determin the particles to be re- covered of each fraction which does contain particles of the components to be sorted out. Thus the largest particles of the respective lighter component, to be sorted out, can be separated from the smallest particles of the respective heavier component to be sorted out. Fig. 4
