The object of this research is the leachinys of pachuk on the GMF SE " VostGOK". The aim of this research - for the improvement of high-quality indexes of leachinys on pachuk intensifying additions, containing a nitric acid urea and biftorid ammonium, were offered.Theoretikal and practical results are making use of a composition of additives (mixture nitric asid urea and biftorid ammonium) in pachukovom mode has not given possibility to reach design extraction of the uranium confirmed with using autoklave mode of processing of charge of ores. Thus pachukovy variant of lixiviating leads to formation the silicon asid which polymerisation in a sorbent leads to its gradual poisoning and decrease soiption ability in reletion to uranium (sorbent depression). The increase in the maintenance of iron in a liquid phase of pulp promotes growth of its absorption by anionite and to increase of its maintenance in the commodity regenerates that finally leads to deterioration of the prepared products on gland and, probably, other limited impurity (Zr, Ti, Si and other). Application of the intensifying reagents containing fluorine-ion, despite presence of passivators, leads to increase in speed of corrosion in the sulphuric acid environments and to decrease in service life of the process equipment. For the pulps containing fluoric connections, before their dump additional actions for their neutrolisation should be provided. The application sphere - the spent research work is the precondition of consideration of technology of processing of ores pachukovom mode as alternative current on GMF to 2 phasic scheme avtoklavno-pachukovogo lixiviating.
