Abstract
967,823. Extracting molybdenum and zirconium values using esters of phosphorus acids. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 9, 1962 [Oct. 13, 1961], No. 36918/61. Heading C2C. [Also in Divisions C1 and G6] Molybdenum or zirconium values are extracted from an aqueous nitric acid solution thereof by contacting the solution with an immiscible liquid organic phase which contains a hydrocarbon-substituted phosphorus acid having at least one hydroxyl group attached to the phosphorus atom, such phosphorus acid being insoluble in the solution. Suitable phosphorus acids include mono- and di alkyl or aryl, and alkyl aryl, phosphoric and phosphonic acids, specified acids being mono-dodecyl, mono-heptadecyl-, di-2- ethyl hexyl-, and di-n-decyl phosphoric acids. Suitable organic diluents for the phosphorus acid. are e.g. kerosene, benzene, hexane, and dodecane. The initial nitric acid solution may contain nuclear fission products. The Mo and Zr values may subsequently be extracted from the organic phase as fluoride complexes (see Division Cl).
