Mining Uranium How Safe Is It And Why Do It Myths And

there are three ways to mine uranium ore: the first method is open when the uranium ore is close to the ground. with this method, a quarry is dug up by bulldozers, the ore is extracted with excavators and transported to the processing complex. the second method is underground and used with deep ore occurrence. this method is more expensive and uranium mines most uranium ore is mined in open pit or underground mines. the uranium content of the ore is often between only 0.1% and 0.2%. therefore, large amounts of ore have to be mined to get at the uranium. In the early years up until the uranium was predominantly mined in open pit mines from ore deposits located near the surface.

Uranium Mining By In Situ Leaching

In india, uranium occurrences of almost all the above types are reported in different parts of the country. occurrence of uranium in the above types call for application of conventional mining methods like open pit mining or underground mining and uranium can be mined in several ways: open pit mining; underground mining, and in-situ leaching. open pit uranium mining involves drilling and blasting to expose the ore body. loaders and dump trucks are then used to remove the uranium ore and carry it out of the mine.
