    2020-6-25  Uranium bearing ore was discovered at the site in 1906. The site was initially mined intermittently by private companies from 1909 to 1931, when ore was first sent to Sydney then later to Dry Creek South Australia to produce radium. Between 1952 and 1961 the principal mining activities were undertaken by the South Australia Government.

Where orebodies are deeper, underground mining is usually employed, involving construction of access shafts and tunnels but with less waste rock removed and less environmental impact. In either case, grade control is usually achieved by measuring radioactivity as a surrogate for uranium concentration.*...
  • How Uranium Mining Works HowStuffWorks

    Like other metals, uranium occurs naturally in rocks on the Earth's surface and can be extracted through uranium mining. Miners originally discovered uranium alongside radium, another element that was used as glowing, decorative paint (at least until people realized its harmful, radioactive effects). Uranium hit the market as a decorative glaze ...

  • Radioactive Waste From Uranium Mining and Milling ...

    Uranium eventually decays to radium. Radium decays to release a radioactive gas called radon. Open pit uranium milling and in situ mining sites do not pose a significant radon risk to the public or to miners; the radon disperses into the atmosphere. In the past, the waste rock produced by underground and open pit mining was piled up outside the ...
