Geology of Uranium Deposits - World Nuclear Association

Uranium Minerals. The major primary ore mineral is uraninite (basically UO 2) or pitchblende (U 2 O 5.UO 3, better known as U 3 O 8), though a range of other uranium minerals are found in particular deposits. These include carnotite (uranium potassium vanadate), the davidite-brannerite-absite type uranium titanates, and the euxenite-fergusonite ...

URANINITE (Uranium Oxide) - Amethyst Galleries' Mineral ...

Uraninite is a highly radioactive and interesting mineral. It is the chief ore of uranium and radium, which is found in trace amounts. Helium was first discovered on the earth in samples of uraninite. Radium and helium are found in uraninite because they are the principle products of uranium's decay process.

Uranium leeching process and in-situ mining (Patent ...

A process is described for the in-situ leaching of uranium from a subterranean ore deposit employing a lixiviant containing a carbonate leaching agent and an oxidizing agent. The lixiviant is heated to a temperature of at least 110* F. Prior to injection into the subterranean ore deposit.

Mineralogy and uranium leaching of ores from Triassic ...

The effect of ore mineralogy and mineral liberation on the leaching behaviour of uranium is not well defined. The procedure of uranium extraction must be designed to fit specific characteristics of the ore; however the general scheme of the process is similar for most of the ore materials.
