Uranium ore for silver in the 16th century. F.E. Brückmann made the first mineralogical description of the mineral in 1727 and the vein deposit Jachymov in the Czech Republic became the type locality for uraninite. In 1789 the German chemist M. H. Klaproth discovered the element of uranium in a sample of pitchblende from the Johanngeorgenstadt vein deposit. The first industrial production of uranium was made from the Jachymov deposit and Marie and Pierre Curie used the tailings of the mine for their discovery of polonium and radium. Vein deposits consist of uranium minerals filling in cavities such as cracks, veins, fractures,
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
