Governing Uranium. U ranium is a common element, found in the Earth's crust in concentrations ranging from upwards of 20 per cent uranium or 200,000 parts per million (ppm) in very highgrade ore such as that found in Canada's Athabasca Basin, to % (100 ppmU) in very low grade ore such as that found in Namibia and ppmU found in ...

The uranium is in discrete uraniumenriched zones that are being mined separately from the copper ore and stockpiled. An environmental impact assessment of the uranium project was approved in December 2008 and treatment of uranium ore to produce 700 tU/yr was planned from 2010.

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

Jun 29, 2015 · Uranium recovery focuses on extracting natural uranium ore from the earth and concentrating (or milling) that ore. These recovery operations produce a product, called "yellowcake," which is then transported to a succession of fuel cycle facilities where the yellowcake is transformed into fuel for nuclear power reactors.
