Uranium ore

Uranium ore deposits are economically recoverable concentrations of <a href="/facts/Uranium/n2sGWBzU">uranium</a> within <a href="/facts/Earth%2527s_crust/VSy2u31r">Earth's crust</a>. Uranium is one of the most common <a href="/facts/Chemical_element/0jducgWD">elements</a> in Earth's crust, being 40 times more common than <a href="/facts/Silver/xXe41BGg">silver</a> and 500 times more common than <a href="/facts/Gold/1znknojp">gold</a>. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the concentrations are adequate to form an economically viable deposit. The primary use for uranium obtained from mining is in fuel for <a href="/facts/Nuclear_reactors/8xqjIbge">nuclear reactors</a>.
Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, <a href="/facts/Kazakhstan/Vfs8NI6e">Kazakhstan</a>, and Canada. To date, high-grade deposits are only found in the <a href="/facts/Athabasca_Basin/hhGDNwLR">Athabasca Basin</a> region of Canada. [disputed – discuss] Uranium deposits are generally classified based on host rocks, structural setting, and mineralogy of the deposit. The most widely used classification scheme was developed by the <a href="/facts/International_Atomic_Energy_Agency/o84JrwQ7">International Atomic Energy Agency</a> and subdivides deposits into 15 categories.
