Abstract
1455590 Metal oxides or hydrides by reduction in organic media SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ BV 20 Dec 1973 [22 Dec 1972] 59102/73 Heading C1A [Also in Division C7] Metal values in the form of oxides or hydrides are recovered from liquid organic media containing compounds and/or complexes of the metals by treatment with a reducing gas, wherein a fluidized bed of seed particles is maintained by passing the organic medium and/or the reducing gas at a suitable rate upwards through the bed. The seed particles are preferably metal powders of less than 1 mm. size; the preferred reducing gas is hydrogen. The metal values are those of Groups IB, IIB, IIIA to VIIA and VIII and the compounds and/or complexes may be salts of ternary carboxylic acids although other species are also exemplified. The metal-containing organic media may be the result of extraction of the metal values from aqueous solutions into the organic phase, or by direct contact of ores with the organic medium.
