Open pit mining. The Rossing Uranium mine is a low grade Alaskite open pit mine (SJ pit) which is long and 345m deep. Conventional methods including drilling, blasting, loading and hauling are used for mining uranium from the open pit. A total of million tonnes of rock was mined in 2008.
Physically removing the rock ore generally involves either openpit mining or underground mining. • Openpit mining is stripping away or excavating the topsoil and rock that lie above the uranium ore. • Underground mining is extracting rock through a tunnel or opening the side of a hill or mountain. Chemically dissolving the uranium out of ...
Uranium also can be a byproduct of other mineral processing operations. Openpit mining involves the removal of a great deal of overlying rock—known as burden—by drilling and blasting. A significant amount of waste rock also is removed. Steps are cut into the exposed ore body to facilitate ore removal by large loaders and dump trucks.

By 1968 openpit mining operations were begun. At the same time, to overcome the burden of shipping the ore 145 miles to another Utah facility for processing, it was decided to build a new uraniumprocessing mill at Shirley Basin.
The expansion will be followed by a staged development of an open pit, with an eventual target annual output of 750,000t of copper, 19,000t of uranium and 800,000oz of gold. The company also said it is looking at shipping copper concentrate directly to smelters in China, which will cut the cost of producing hodes at the mine.
Orano holds expertise in mining for multiple types of mines, openpit mines for shallow deposits and underground mines for access to deep deposits. The Group is an expert in the in situ recovery technique (ISR) for lowgrade deposits; this technique is used only when the ore is loed between impervious soil layers, as in Kazakhstan and Mongolia.
