Сharacteristic features of material composition of aged pyrrhotine concentrate from technogenic deposit — pyrrhotinestorage № 2 determining the preparability level of this kind of polymetal materials are examined. Perspective directions of development of preparation technology provided essential rise of the level of valued components extraction from difficult technogenic material are presented. Usage of progressive processes and modern equipment (classification in washing cyclones Krebs gMAX using the Cyclowash technology, floatation in flotation machine Wemco SmartCell) provides essential rise of the production processes efficiency.

Technogenic deposits, aged pyrrhotine concentrate, material composition, pyrrhotine, nickel-pyrrhotine concentrate, classification, floatation, grain-size classes, selectance, extraction.
