Uranium processing | Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
