El Sherana
El Sherana is an abandoned uranium mine in the South Alligator River Valley of the Northern Territory, Australia. The deposit was discovered in 1954 by a United Uranium NL exploration team, led by Joe Fischer, with a ground radiometric survey. The site was named after the daughters of a team staff member, William 'Bluey' Halpin Kay - Elvira, Sherryl and Lana. El Sherana operated from 1958 to 1959 and El Sherana West from 1961 to 1964. El Sherana was the largest producer of high grade uranium ore (with minor gold and silver) amongst the mines along the South Alligator River Valley. It had underground and open-cut operations. Production from El Sherana was 38,437 long tons at a grade of 12.42 lb U3O8 per long ton (0.55% U3O8). From El Sherana West, 21,316 long tons at a grade of 18.35 lb U3O8 per long ton (0.82% U3O8) were produced. At El Sherana and El Sherana West, uranium-gold mineralisation occurs in two general settings: at or near the shallow-dipping Koolpin Formation/Coron ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99.2739 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcopyrite
Chalcopyrite ( ) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green-tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides, and sulfates. Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). Is rarely found in association with native copper. Chalcopyrite is a conductor of electricity. Etymology The name chalcopyrite comes from the Greek words , which means copper, and ', which means striking fire. It was sometimes historically referred to as "yellow copper". Identification Chalcopyrite is often confused with pyrite and gold since all three of these minerals have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kakadu National Park
Kakadu National Park is a protected area in the Northern Territory of Australia, southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census. Water buffalo, which are now an environmental pest, were released in the area in the late 19th century, and missionaries established a mission at Oenpelli (present-day Gunbalanya) in 1925. A few pastoralists, crocodile hunters and wood cutters made a living at various times during the 20th century. The area was given protected status bit by bit from the 1970s onwards. The park is located within the Alligator Rivers Region of the Northern Territory. It covers an area of , extending nearly from north to south and over from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second largest national park in Australia (after the Munga-Thirri–Simpso ...

Australian Conservation Foundation
The Australian Conservation Foundation (ACF) is Australia's national environmental organisation, launched in 1965 in response to a proposal by the World Wide Fund for Nature for a more co-ordinated approach to sustainability. One high-profile campaign was ‘Save the Whales’, which ended commercial whaling in Australia, following widespread protest against the huge slaughter. Another was to protect the vulnerable Great Barrier Reef by classifying it as a Marine Park, from which mining, drilling and trawling were banned. By 2000, ACF initiatives extended across a wide range of agendas, such as climate change, clean energy, rainforest preservation, greenhouse pollution and land tenure reform in the indigenous communities. ACF is an independent, non-partisan, non-profit organisation focused on advocacy, policy, research and community organising, with a membership of 700,000. Its President, as of 2022, is Mara Bún.

Coronation Hill
Coronation Hill is a sandstone outcrop within Kakadu National Park in the Northern Territory of Australia. The area had been briefly mined for uranium at El Sherana in the 1950s and in 1988 proposals for new mining of gold were made. When mining was proposed in 1988 the area existed as an excised zone of Kakadu National Park and was added to it after the proposal was defeated. Political importance The Australian Government established the Resource Assessment Commission to provide a report to inform best decision making about new mining in the area. Environmental, indigenous rights and social campaigns fought against allowing mining. Opposed environmental campaigns came from many organisations including the Kakadu Action Group founded by Lindsay Mollison, part of the Australian Conservation Foundation. After some years of community debate the proposal was vetoed, despite internal disagreement, by then Prime Minister, Bob Hawke, in a Cabinet Meeting in May 1991. His actio ...
