The product of uranium mining is normally uranium oxide concentrate – U 3 O 8 – which is shipped from the mines in 200-litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings.

Recent uranium mining. Canada's uranium production in 2001 was about 12,500 tonnes uranium (tU), one third of world mine output, all from mines in northern Saskatchewan. By 2007, the share of world uranium production had decreased to 23%, with just under 9500 tU produced that year in the country. Canada's uranium ore reserves are about 14% of ...

The occurrence of uranium in different types of rocks is given in Table 2.1. Uranium does not occur in native elemental form. It is chemically reactive and has great affinity for oxygen. Uranium exists in multiple oxidation states, say, +3, +4, +5, and +6, but the +4 and +6 states are predominant among them [ 3 ].
