Uranium from Phosphates

Rock phosphate deposits contain many million tonnes of uranium which may be extracted as a by product of making fertilisers Some 20 000 tonnes of uranium has already been obtained from these rock phosphate deposits but the process became uneconomic in the 1990s Higher uranium prices and process refinements have changed the economic situation.
