METHOD OF SEPARATING RHENIUM AND MOLYBDENUM Russian patent published in 2007 - IPC C01G47/00 C01G39/00

Abstract RU 2306260 C1

FIELD: hydrometallurgy of rare and scattered elements.

SUBSTANCE: invention has for object isolating and concentrating rhenium and separating rhenium and molybdenum when processing various molybdenum-containing industrial products. Method according to invention comprises sorption of rhenium form solutions followed by desorption thereof. The latter operation is accomplished with mixture containing phosphoric acid hexabutylthiamide (1-3 % v/v) and aliphatic C₆-C₁₀-alcohol.

EFFECT: increased degree of recovery of rhenium from initial aqueous process solutions.
