FIELD: mineral concentration; applicable in processing of technogenic deposits. SUBSTANCE: method includes preliminary treatment of pyrite cinders by method of sulfoagglomeration. Charge of sulfoagglomeration consists of pyrite cinders, sulfur-containing material and coke. Obtained agglomerate is crushed, ground and separated, for instance, by flotation with separation of copper and iron concentrates. Sulfur-containing material is used in the form of tailings of concentration mills, and/or lean pyritic ore, etc. EFFECT: higher recovery of nonferrous and precious metals with complex utilization of pyrite cinders; improved ecology. 8 cl, 1 ex
