METHOD OF CONCENTRATING COMPLEX ORES Russian patent published in 1998 - IPC

FIELD: mining industry, in particular, methods of concentration of complex ores and flotation tailings of these ores; may be used in mineral concentration, construction and other branches of industry. SUBSTANCE: method of concentration of complex copper sulfide-apatite-titanomagnetite ores includes grinding and wet magnetic separation. After grinding, the ores and also tailings of copper flotation of these ores are concentrated in aqueous medium on spiral separators and concentrators and then subjected to wet magnetic separation with low and then with high intensities of magnetic field and to concentration on concentrators. EFFECT: higher quality of produced concentrate, increased recovery of minerals, utilization of large volumes of concentration tailings and improves sanitation of ecological conditions in the regions. 1 dwg, 1 tbl
