Description: Production of black oxide from torbernite was studied on a laboratory scale from the standpoint of uranium extraction, reagent requirements, and removal of impurities. A small portion of the material was examined for its mineral constituents, using optical properties, X-ray diffraction patterns, and chemical analysis for identification. About 50% of the material was quartz; 30% green crystals of a copper-uranium phosphate; 10% of a black mineral, which was not identified, but which appeared to be an oxide mixture of nickel, cobalt, copper, and molybdenum; and small amounts of gibbsite, laterite and feldspar. There were no lower oxides of uranium in the sample.
