'''Jurbanite''' is a sulfate mineral with the chemical formula AlSO<sub>4</sub>(OH)·5H<sub>2</sub>O. Its molecular weight is 230.13 g/mol. It crystallizes in the monoclinic system and is dimorphous with the orthorhombic mineral rostite.<ref name=Mindat/> Jurbanite occurs as a secondary (post-mine) mineral in mines containing sulfide minerals.<ref name=Webmin/>
Jurbanite was first described for an occurrence in the San Manuel mine of Pinal County, Arizona and first described in 1976s. It was named for Joseph John Urban, the mineral collector who discovered it.<ref name=Mindat>[http://www.mindat.org/min-2125.html Mindat.org - Jurbanite]</ref>
