COLLECTIVE FLOTATION OF THE SULFIDE/OXIDIZED ORES OF THE ZHIREKENSKOE DEPOSIT

摘要

The expansion of molybdenum production and the increase of the output of the individual molybdenum mines often involve the working of leaner and more-difficult-to-concentrate segments of the ore body, particularly the segments that are rich in oxidized molybdenum. The change of the relationship between the sulfide molybdenum and the oxidized molybdenum content leads to disruption of the technological process in the case of separate (sulfide and oxidized) flotation.From this point of view the development of the collective sulfide/oxidized flotation scheme with the obtaining of high-quality concentrates is of great practical importance, since this will make it possible to significantly simplify the modification of the process in case of change of the composition of the ore, will reduce the scope of the flotation operation, will reduce the electric power consumption, and will increase the output of high-quality concentrate.
