ADDIS ABABA, Ethiopia, May 15 (AP) -- Emperor Haile Selassie announced today in an interview that some of the best uranium ore in the world had been discovered in his remote East African realm.


The beneficiation methods for Ethiopian Kenticha pegmatite–spodumene ores were assessed through mineralogical and quantitative analyses with X-ray diffraction (XRD) and energy-dispersive X-ray fluorescence (EDXRF). The tantalite in the upper zone of the Kenticha pegmatite–spodumene deposit is 58.7wt% higher than that in the inner zone. XRD …

@article{osti_4832124, title = {BENEFICIATION OF URANIUM ORES}, author = {Tame, K E and Rosenbaum, J B}, abstractNote = {32p. A summary of the history and state of the art of physical beneficiation of uranium ores is presented along with a detailed description of research on concentration of uranium ores by attrition grinding.


Mulugeta et al. focused on the leaching of uranium and thorium from a high-grade Ethiopian tantalite ore using sulphuric acid. The amount of uranium leached increased from 69.1% at a contact time ...


uranium oxide or uranium oxide equivalent. Uranium oxide is a generic term for a number of common chemical forms of uranium, the most common being U 3O 8. Yellowcake is another generic term, used to describe the yellow powder generated as the end product of uranium beneficiation. The purity of yellowcake typically ranges from 60 to 75 percent U 3O


Congress: Wastes from the Extraction and Beneficiation of Metallic Ores, Phosphate Rock, Asbestos, Overburden From Uranium Mining, and Oil Shale (U.S. EPA 1985a). In July 1986, EPA made a regulatory determination that regulation of extraction and beneficiation wastes under Subtitle C was not warranted (51 FR 24496; July 3, 1986).


Abstract. Investigations are presented of methods for the physi cal beneficiation of low-grade and other uranium ores. The investlgations which have been in progress since September 1952 cover work done on a variety of natural ores, as well as a certain amount of basic research on mixtures of synthetic or high-grade natural uranium minerais with various gangues.


Ethiopia has ambitious plans of generating 1,200mw of electricity from nuclear energy in 25 years. Russia and Ethiopia signed a memorandum of understanding in 2019, setting out a three-year plan to lay the ground for creating a centre for nuclear science and technology.


Peter H. Woods, in Uranium for Nuclear Power, 2016 6.4.2 Ore beneficiation (including ablation, radiometric, and gravimetric sorting). Ore beneficiation refers to the selection and collection of higher-grade ore fragments or rejection of lower-grade fragments from ROM ore. The upgraded ore will have a higher grade, and therefore require a smaller-scale processing plant, perhaps with different ...

Steps used in beneficiation depend on the type of rock. A typical beneficiation ... uranium and its decay products. Some phosphate rock also contains elevated levels of thorium and its 7/93 (Reformatted 1/95) Mineral Products Industry 11.21-3. daughter products. The specific radionuclides of significance include uranium-238, uranium-234,


The beneficiation methods for Ethiopian Kenticha pegmatite-spodumene ores were assessed through mineralogical and quantitative analyses with X-ray diffraction (XRD) and energy-dispersive X-ray fluorescence (EDXRF). The tantalite in the upper zone of the Kenticha pegmatite-spodumene deposit is 58.7wt% higher than that in the inner zone. XRD analysis revealed that the upper zone is dominated …

The estimated Tiris operating cost now stands at US$19.40/lb U 3 O 8 . Mining lease application submitted for Tiris uranium mine project : On May 24, 2017, Aura Energy Limited announced that it has submitted the mining lease application for its Tiris project.


Toro Energy Limited (ASX:TOE) announces Beneficiation and Process Design studies ('Studies') for the Company's owned Wiluna Uranium Project in Western Australia have highlighted the opportunity to substantially reduce the size and cost of the processing facility.


In tantalite concentrate, the uranium concentration (the three naturally occurring U radioisotopes) was near 0.5%, which is a relatively high percentage of uranium, actually higher than the ore ...


The cash-cost of production, which includes a 3% net smelter royalty payable to the State, was estimated at US$21.62 per pound of uranium (U 3 O 8) net of a vanadium by-product credit. The flat-lying, near-surface nature of the uranium-bearing gravel layer provides the operator with the option of mining the highest-grade area of the deposit ...
