摘要：
The study data on mineralogy and process properties of magnetite ore of the Poperechny deposit (Maly Khingan) are presented. The mineral composition, structure and texture of the ore are analyzed, and signs of its contact-metasomatic nature are determined. Two generations of magnetite are revealed. Extractability of iron at recovery of 94.39% is proved experimentally, including 78.72% to concentrate and 15.67% to middlings. Iron recovery of rougher concentrates is 40.74-42.74%. It is found that the ore contains noble metals: gold is represented by free grains 0.05-0.2 mm in size; platinum and platinoids (Os, Ir, Ru) are revealed as micronodules in magnetite jaspilite and dolomite in concentrates.
