METHOD OF OBTAINING MINERALS AND DEVICE FOR ITS REALISATION Russian patent published in 2008 - IPC C30B33/04 B01J19/08 

FIELD: chemistry; mechanics.

SUBSTANCE: method of obtaining minerals is realised in neutron reactor flow, minerals being placed in layers between layers of substance or mixture of substances, containing elements, absorbing thermal and resonance neutrons, layers being separated with aluminium interlayer and surrounded with filtering unit from substance or mixture of substances, containing elements, absorbing thermal and resonance neutrons, with cadmium screen, layer thickness and geometrical parameters of unit are calculated in such way that at the moment of exposure to radiation mineral temperature does not exceed 200°C, and "Ф_б.н./Ф_т.н." ≥10, where "Ф_б.н." is density of flow of fast neutrons with energy higher than 1MeV, "Ф_т.н." - density of thermal neutrons flow. Described is device for mineral irradiation, containing hermetical filtering unit, filled with substance or mixture of substances, containing elements, absorbing thermal and resonance neutrons, with axial hole, in which cadmium screen is placed and also placed is a case open from the bottom for partial filling with heat carrier, operation volume of case is filled with minerals, placed in layers between layers of substance or mixture of substances, containing elements, absorbing thermal and resonance neutrons, layers being separated with aluminium interlayer.

EFFECT: reducing cycle of production of minerals with higher jewelry value.
