Uranium mining – what method works best? - Nuclear ...

The decision as to which mining method to use for a particular uranium deposit is governed by the nature of the orebody, safety and economic considerations. Both excavation and in situ techniques are used to recover uranium ore. In the case of underground uranium mines, special precautions (consisting primarily of increased ventilation) are required to protect against airborne radiation ...

Uranium Mining Overview - World Nuclear Association

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade. Other mines however can operate successfully ...

Uranium Ore - an overview ScienceDirect Topics

IV.B Mining. Uranium ore is mined using open pit and underground methods similar to those used for mining other minerals and coal. In situ leaching of permeable sandstone deposits accounts for an increasing share of production. The depth, grade, and size of the deposit determines the type of mining to be used. Depths of open pit uranium mines range from a few feet to depths in excess of 300 ft ...

4 Uranium Mining, Processing, and Reclamation

For uranium ore deposits, the choice of mining methods and processing options is very deposit-specific and dependent on many variables such as the quality and quantity of the ore, the shape and depth of the ore deposit, site-specific environmental conditions, and a range of other factors. Accordingly, the description of how uranium mining is undertaken in this report is generalized and at a ...

Copper Mining and Production Processes Explained

Mining. The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore. An ore is a rock that contains enough metal ...
