Comparative life-cycle assessment of uranium extraction processes

A typical ore with a uranium concentration of 0.2% has a uranium-238 activity of about 25,000 Bq/kg. The total activity calculated including all the uranium-238 daughter products and the uranium-235 decay chain, therefore, exceeds 360,000 Bq/kg, while the mean activity of the earth's crust is below 2000 Bq/kg.

Uranium processing

Uranium processing - Leaching, Extraction, Purification: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed …

AU9918804 BEHAVIOUR OF POLONIUM-210 DURING …

uranium-rich ores contain about 100 ig of polonium per tonne of ore. When copper ores containing uranium minerals are processed, the polonium-210 reports to the anode slimes. During anode slimes treatment, any polonium released into process liquors and solids can potentially result in unacceptably high levels of radioactive contamination in

URANIUM MILLING AND PROCESSING FACILITIES

Uranium Processing

Uranium primarily exists in nature as an oxide and almost never in its free elemental form. It can combine with oxygen in any stoichiometry, but the most common forms are UO 2 (uraninite) and U 3 O 8 (pitchblende).. 5.2.1 Acid Leaching. Acid leaching involves treating the finely ground uranium ore slurry with sulfuric acid at elevated temperatures, usually in the …

Guidebook on the development of projects for uranium …

The end product of a uranium development project is a saleable uranium concentrate. Saleability is determined by the acceptance of the market to buy the product at a price which provides a net positive benefit. Bringing a uranium operation into production involves a sequence of interrelated steps. These are outlined in the simplified diagram of ...
