Detailed explanation-1: -Uranium ore deposits are known to occur in igneous, sedimentary, and metamorphic rocks, and in many different types of rock within each of these classifications.
Detailed explanation-2: -Uranium is found in small amounts in most rocks, and even in seawater. Uranium mines operate in many countries, but more than 85% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia.
Detailed explanation-3: -Uranium is a naturally occurring radioactive element that is present in nearly all rocks and soils; it has an average concentration in U.S. soils of about 2 pCi/g (3 ppm) (du Preez 1989; NCRP 1984a).
Detailed explanation-4: -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 pumping it to the surface.
