Uranium extraction of 95% has been obtained from samples of Temple Mountain ore by a cyclic test procedure in which the new feed was not roasted. This procedure involved acid leaching the ore, flotation and roasting of the carbonaceous material, and acid leaching the roaster calcine.

A resin-in-pulp process was developed using a series of fixed-screen or Winchester cells. Various laboratory and pilot plant models were constructed and tested under simulated plant conditions. The fixed-screen device proved very effective in the recovery of uranium and/or vanadium by a continuous, resin-in-pulp process.

Report discussing spectrographic analyses of rocks, ores, mill products, and smelter products. From Abstract: "The analyses are grouped by states and by major raw mineral raw materials. The samples vary widely in character and in kind of material. They were analyzed chiefly by spectrographic methods, the accuracy of which increased during the later stages of the work."

A series of organic reagents for the collection and flotation of several secondary uranium minerals has been developed, this being the mono-alkyl nitrogen substitutions of the dithiocarbamate grouping with a chain length of at least eight carbon atoms. In flotation tests, using the potassium salt of n-decyl dithiocarbamate as collector, high recoveries of autunite have been obtained from mixtures of finely-ground synthetic autunite and silica sand. Certain base-metal salts added as conditioning agents have increased the collecting properties and selectivity of the dithiocarbamates in the flotation of both autunite and carnotite. In single batch and locked tests, using lead as the base metal ion, recoveries of over 95 percent of the uranium have been obtained, with ratios of concentration as high as 13:1. Preliminary tests on natural ores show encouraging results; the problems of liberation and conditioning must be solved for each ore. (auth)
