ウラン鉱の粗製錬

抄録

Concerning with the milling of uranium ores, the technical and economical problems were summarized First, the data, which seem to have been reasonably estimated, are presented on the inferred uranium ore reserves, and the ore production and the demands of uranium at present and in future, Second, brief explanation of are dressing and milling of the ores is given, and outline of each process-crushi ng and grinding, leaching, liquid-solids separation, uranium recovery from leach liquors, precipitation, and so on, is described mostly for the case of the sulfuric acid leaching method which is currently adopted most commonly. Third, the milling processes of Beaverlodge mill, Canada; Mary Cathleen, Australia; Kvarntorp, Sweden were explained as the examples. Finally, uranium ores in the Ningyo-toge area which has the biggest uranium ore potential in Japan, is briefly described on the ore deposits, properties of the ores, and results of the milling.
