In a few places, uranium can be dissolved from ore directly, by pumping mining solutions underground, bringing it back to the surface and extracting the dissolved uranium. Uranium milling. The ore is crushed in a mill and ground to a fine slurry. Acid is added to the slurry to remove the uranium from the other minerals.

A crucial step of nuclear fuel manufacture is the co-milling of uranium and plutonium oxides to obtain a targeted particle size and excellent mixing. However, the scale-up …

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 1960's uranium was predominantly mined in open pit mines from ore deposits located near the surface.

For instance, increase in feed flow velocity (Q S) from 1.1 × 10 − 5 m 3/ s to 2.2 × 10 − 5 m 3/ s in the case of static conditions, caused > 30% increase in uranium leaching efficiency, while in the case of rotation frequency of 1500 rpm, an identical increase of Q S caused only 5% increase in efficiency of uranium leaching. A similar ...
