Uranium tile Uranium tile Uranium tiles have been used in the ceramics industry for many centuries, as uranium oxide makes an excellent ceramic glaze, and is reasonably abundant on the earth's crust. Not long after Henri Becquerel discovered radioactivity in uranium salts, Madame Curie discovered both polonium and radium as two new radioactive elements also present with uranium. The relatively high specific activity and moderate half-life of 1,600 years of Ra-226, the main radioisotope of radium found in uranium ore, made for a material which when mixed with a phosphor allowed for a glow-in-the-dark substance. Thus, in addition to its medical usage,
Beverley Uranium Mine The uranium mineralisation (mainly coffinite) is hosted by loose sands in the channel of a former river. The ore bearing horizon is now at a depth of about 100 to 150m. The deposit is estimated to contain 21,000 tonnes of uranium oxide for a mine life of 15 to 30 years. Uranium is extracted by in-situ leaching, involving the injection of a fluid containing sulphuric acid and hydrogen peroxide into the ore-bearing permeable horizon to mobilise the uranium. The fluid is then recovered and uranium is extracted at a central plant using ion-exchange. The final concentrate is trucked to Port
