The main directions of development of beneficiation complex of Lavozersky mining and concentrating complex, based on optimization of processes of ore preparation and gravity beneficiation are described. Expedience of reduction of ore size, crushed to the I stage has been shown. Technology of reduction of content of contaminants in finished concentrate, of increase of ore quality entering at the factory on the base of usage of heavy medium separation and of tailing processing of beneficiation with nepheline concentrate fabrication has been proposed.
