Source: Geoscience Australia. Canadian mines have pushed it up again. Over two-thirds of the world's production of uranium from mines is from Kazakhstan, Canada and Australia. Reflecting the international and diverse nature of the industry, a series of mining case studies is presented covering the commodity range from iron ore to diamonds extracted by operations located in all corners of the world. The Olympic Dam ore body begins about 300 metres below the surface and continues to a depth of more than 1 kilometre. Geotech, engineering, geology and survey . Where the ore exists in an underground aquifer, as is the case at Beverley and Beverley North, oxygen and a weak acid mining solution is pumped through the ore body to dissolve the uranium minerals. Industry experts have contributed 77 chapters. 2015, 2016). The full energy accounting for direct uranium production at Olympic Dam would need to consider a detailed analysis and breakdown of the milling, metallurgical and smelting process, which is obviously impracticable.

Its mission is to be the trusted source of information on Australia's geology and geography to inform government, industry and community decision-making. There are also 10 intake shafts and 20 exhaust shafts which were raise bored from the underground mine. Concepts of ore genesis and emplacement often have to be modified as drill- ing and mining proceeds, and the final picture may be quite different from the original idea. Cave mining methods will be the underground method of choice in the future. Abstract. At the Beverley, Four Mile and Honeymoon deposits in-situ mining methods are used. The method at Olympic Dam (and proposed for Jabiluka) is known as long-hole open stoping. September 17, 2011 - 12:01AM. The empirical Mathews stability method has been applied to open stope stability forecasting at Olympic Dam for the more than 20 years.

We recognise and respect the cultural connections as the Traditional Owners and occupants of the land and waters of South Australia, and that they continue to make a unique and irreplaceable contribution to the State. While South Australia's largest copper mine, Olympic Dam, may not be appropriate for this method, Thor Mining's Kapunda and Alford projects look promising for in-situ recovery. Olympic Dam is the type deposit for a class known as Iron-Oxide-Copper-Gold or (IOCG) for short. The dissolved uranium is then pumped to the surface, where it is taken out of solution through the ion exchange (IX) process, dried and packaged . A detailed database of stope performance and ground condition information was established for each stope. South Australian Chamber of Mines and Energy is acknowledged as the provider of this resource. Conservationists want BHP to stop using evaporation ponds at Olympic Dam that kill hundreds of birds, including threatened species. The location is 5kms from existing 275kV and 132kV power lines, and 13kms from the town of Roxby Downs (Figure 2). #2 Olympic Dam Mining method: sublevel stoping. Uranium is a naturally-occurring element in the Earth's crust. These are large Formation of the Olympic Dam breccia and Mineral Deposit intrusive deposits which are characterized by the presence of hematite (an Iron Oxide) alteration and breccias. Figure The type of tailings dam a mining company builds is directly related to the safety of the structure. An Olympic Dam Task Force was even set up to streamline the process further. By-production of uranium (where uranium is produced in combination with other metals such as copper and gold) has been fairly constant over time at around 10% of output and today mainly reflects the production levels at the Olympic Dam mine in South Australia (copper and gold) rather than South Africa (gold). Olympic Dam Expansion - ODX - would place the operation in the top three globally, adding 515,000 tonnes of copper . It is mired in controversy. To make nuclear fuel from the uranium ore requires first for the uranium to be extracted from the rock in which it is found, then enriched in the uranium-235 isotope .
