In page Uranium:

"

Uranium metal reacts with almost all non-metallic elements (except noble gases) and their compounds, its reactivity increasing with temperature.[7] Hydrochloric and nitric acids dissolve uranium, but non-oxidizing acids other than hydrochloric acid attack the element very slowly.[1] When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium dioxide.[2] Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.[citation needed]
