There is given generic approach to selection of man-induced feedstock's enrichment schemes, including: slags, clinkers, slums etc., demonstrated a ranking system of possible enrichment methods according with chemical composition of man-induced materials. On the base of this ranking and examination of mineral and phase composition of man-induced waste as well its physical and mechanical properties and possibilities of selective disintegration were developed principles and directions of man-induced feedstock enrichment. There is presented estimation of existing treatment schemes.
