Abstract. In conditions of decreasing mineral raw quality coupled with increasing of its impoverishment while applying high-quality system of deposits developing there have been proposed approaches to management of ore quality by formation of ore flow on its way to separation using radiometric preconsentration of ore mass directly after its extraction. The paper using examples of economic evaluation of development of one of the poor apatite ores fields shows that it is possible to form the ore of certain quality providing an increase of profit at the expense of decreasing the commodity output price. This is possible due to principles of ore quality management and applying radiometric pre-separation based on large-portion sorting and scrap separation in the technological cycle.
Keywords: decreasing of mineral raw quality, management of ore quality, radiometric separation
