Openpit and underground mining methods, both of which rely on physical extraction to obtain raw uranium ore, are commonly referred to as conventional mining methods. The reliance on chemical or other means to extract uranium are referred to as unconventional mining methods, even though they may have been used as extraction processes for decades.
Uranium Mining Although extensive ore reserves in the area will require underground mining methods, significant ore reserves were also found near the surface which can be mined by open pit methods. All ore presently being mined by Petrotomics Company is by open pit under contract to Plateau Construction Company of Rawlins, Wyoming.
Open Pit Uranium Mining. As with other types of hard rock mining there are several methods of extraction. In case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of %.
Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.
Depending on the deposit, uranium is mined in one of three ways: open pit, underground, or in situ recovery. Open pit. When uranium is found near the surface usually no more than 100 meters deep it can be extracted via open pit mining. In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed.

Successful Legacy of Insitu Recovery of Uranium. One of the best kept secrets in Texas is that uranium has been continually mined since the late 1950s. Uranium mining was initially conducted by openpit mining followed by conventional milling to produce "yellowcake" which is harnessed to produce electrical energy in nuclear power plants.
After locating uranium deposits and obtaining appropriate permits, a company will begin to mine. There are a few ways to extract uranium from the ground: openpit mining, underground mining and insitu recovery.. Mining methods depend on the type of deposit, whether it''s suspended in water and the geography of the area.
May 18, 2011· Most uranium ore is mined in open pit or underground mines. The uranium content of the ore is often between only % and %. Therefore, large amounts of ore have to be mined to get at the uranium. In the early years up until the 1960''s uranium was predominantly mined in open pit mines from ore deposits located near the surface.
CONVENTIONAL MINING AND MILLING OF URANIUM ORE Introduction. Production of uranium concentrates, in the form of U3O8, or "Yellowcake" as it is commonly referred to in the industry, from ore which is mined by open pit or underground methods and processed to recover uranium, employs technology and methods common to the mining industry.
Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
Mining of low grade uranium sandstones in the Jenkins open pit mine in the Shirley Basin, Wyoming was troubled by slope failures and wet conditions in the pit. Since the mine was expanding toward a river, the possibility of drainage from this river into the mine raised serious concern during the mine planning.
