Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite and coffinite.
Basically in Pakistan uranium is deposited in three types Uraninite, Pitchblende and Coffinite.
Fluorapatite, zircon, Nb-Ta-Ti oxides, xenotime-(Y), monazite-(Ce), uraninite and coffinite are common accessory minerals.
The high tenor and speed of the uranium extraction suggest the Theseus mineralisation consists predominantly of uraninite and coffinite and is readily available for leaching.
These contain quartz and sulphide veins and are characterized by a collection of uranium minerals such as pitchblende, coffinite, uraninite and black U-oxides (parapitchblende) (Arribas, 1962), being the pitchblende usually replaced by sulphides, especially pyrite and melnikovite.
Associated minerals are: pascoite, sherwoodite, selenium, bariandite, devilline, rossite, hewettite, carnotite, clausthalite, coffinite, tyuyamunite, uraninite, corvusite, montroseite, roscoelite, galena, pyrite and tennantite.
The most common uranium mineral is pitchblende, with lesser concentrations of coffinite and brannerite.
Collecting crystals is a popular Swiss hobby, and many displays include minerals -- such as zircon, coffinite, carnotite, monazite, brannerite, titanite and pitchblende -- containing radon-emitting uranium or thorium.
