PHOTOCHEMICAL REACTOR FOR SEPARATION OF ELEMENTS AND THEIR COMPONENTS FROM SOLUTIONS Russian patent published in 2003 - IPC

FIELD: hydrometallurgy. SUBSTANCE: proposed reactor is equipped with radiation chamber with elliptical reflector with optical radiation source and optical radiation transformer located in its focal lines ; reaction chamber is coaxially located in transformer; dye solution and reagents are pumped through this chamber. Radiation transformed by dye solution is brought into focus in reaction chamber at length of wave corresponding to electronic spectrum of absorption band of element or its component separated from solution; photochemical reaction of selective reduction or settling of elements is initiated in presence of reagent. Crystal sediments of solid phase are quickly removed from radiated solution by means of cyclic separator at upper delivery of solution and are settled on walls of changeable storage reservoir. EFFECT: enhanced efficiency; simplified construction; increased degree of extraction of product and improved quality of product. 9 cl, 4 dwg
