Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
1. Introduction. Soon after independence, with the formation of Atomic Energy Commission in 1948 India made a humble beginning of its inspiring atomic energy programme. Consequent to this development, it was felt that the country must have indigenous resources of basic raw materials such as uranium, thorium etc.
Mining and concentrating. Uranium ores occur in deposits that are both near-surface and very deep (e.g., 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores sometimes occur in seams as thick as 30 metres. As is the case with ores of other metals, surface uranium ores are readily mined with large earth-moving equipment, while deep ...
The 10,000 tU/yr deconversion (defluorination) plant was built by Tenex under a technology transfer agreement with Orano, so that depleted uranium can be stored long-term as uranium oxide, and HF is produced as a by-product. The W-ECP plant is similar to Orano's W2 plant at Pierrelatte in France and has mainly west European equipment.
Deep Creek Mining Company uses capital (mining equipment) and labor (workers) to mine uranium ore. Suppose that labor is the only variable input. Complete the following table, which shows the amount of ore produced (measured in tons) when various sizes of crews are used to operate the equipment.
The uranium ore is extracted through mechanical means such as blasting, drilling, pneumatic drilling, picks, and shovels and then transported to the surface. Underground mining is usually used for open pit mining when the uranium is too far below the surface. This type of mining exposes underground workers to the highest levels of radon gas.

Uranium. mining and processing. Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope. The mined ore is crushed and the uranium ...
