Uranium from Phosphates Phosphorite Uranium World

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.

Uranium Mining Overview World Nuclear Association

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.

Radioactive Waste From Uranium Mining and Milling US EPA

Industries in the United States recover uranium from the Earth through mining or chemical extraction. Mining: When uranium is near the surface, miners dig the rock out of open pits. Open pit mining strips away the topsoil and rock that lie above the uranium ore. When uranium is found deep underground, miners must dig underground mines to reach it.

Radioactive Waste and Uranium Mines WorstPolluted

Typically uranium concentrations can be as low as 0.1 to 0.2% in mined ore, meaning that well over 99% of what is mined is rejected after processing. Once mined, ore must be milled to produce useful uranium concentrate. Milling is the process of grinding the ore and adding chemicals, usually sulfuric acid, to extract the uranium it contains.

Uranium mining Wikipedia

Uranium is mined by in-situ leaching (57% of world production) or by conventional underground or open-pit mining of ores (43% of production). During in-situ mining, a leaching solution is pumped down drill holes into the uranium ore deposit where it dissolves the ore minerals.
