METHOD OF PROCESSING PYRITE-CONTAINING TAILINGS AND REBELLIOUS ORES

摘要

FIELD: mineral concentration. SUBSTANCE: method includes preliminary treatment of raw materials by the method of sulfoagglomeration of charge formed of pyrite-containing tailings and/or pyritic ore and coke. Obtained agglomerate is subjected to crushing, grinding and flotation with separation of copper and pyrite concentrate. EFFECT: higher recovery of metals in processing of lean pyritic ores and technogenic deposits of pyrite-containing tailings. 5 cl, 1 ex
