Abstract. The specific activities of natural radionuclides, 232 Th, 226 Ra, and 40 K, in a Chinese iron beneficiation plant and surrounding soil were analyzed with the high purity germanium gamma (HPGe) spectrometer in this study. Average specific activities of 238 U, 232 Th, 226 Ra and 40 K lower than the Chinese averages. To …

Tantalum–niobium ore belongs to associated radioactive ore, which is accompanied by a certain amount of radioactive uranium and thorium. The remaining slag is enriched with a large number of radionuclides; after weathering, natural rainfall, and surface water scouring, radioactive elements such as uranium, thorium, and some …

M.Zeki Dogan. Abstract. In this paper, processing of uranium ores is discussed, namely, beneficiation by radiometric sorting, gravity and magnetic separation methods, flotation and leaching.

In 1995, EPA issued the Technical Resource Document: Extraction and Beneficiation of Ores and Minerals: Uranium as a technical update to provide a means of evaluating wastes that were exempt from or subject to regulation under RCRA (U.S. EPA 1995). During the period 1989 to 1993, EPA worked on a draft scoping report (SC&A 1993), which

A series of laboratory tests showed that uranium is retained in the tributyl phosphate-kerosene solvent extraction stream during re-extraction as a result of the formation of non-water-strippable uranium complexes and the decrease of uranium mass transfer rate at the re-extraction stage, The uranium retained by complexing is held by dibuityl …

The invention relates to a beneficiation process for uranium ores comprising clay and carbonate minerals, the process comprising: performing a hydrocyclone step to obtain a hydrocyclone underflow fraction substantially comprising the uranium component; treating the hydrocyclone underflow fraction to effect a separation of carbonate and uranium …
