CONVENTIONAL MINING AND MILLING OF URANIUM ORE Introduction Production of uranium concentrates in the form of U3O8 or “Yellowcake” as it is commonly referred to in the industry from ore which is mined by open pit or underground methods and processed to recover uranium employs technology and methods common to the mining industry

Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years It is now primarily used as fuel for nuclear reactors that make electricity Uranium can be recovered in two ways by conventional mining of the rock ore or by using strong chemicals to dissolve uranium from the rock that is still in the ground and
