Alunite is a hydroxylated aluminium potassium sulfate mineral, formula K Al 3 (S O 4) 2 (O H) 6. It was first observed in the 15th century at Tolfa, near Rome, where it was mined for the manufacture of alum. First called aluminilite by J.C. Delamétherie in 1797, this name was contracted by François Beudant three decades later to alunite. [8]
Forms a series with natroalunite. Alunite group. Occurrence: Formed between 15 C and 400 C by the action of sulfate, which may be generated from pyrite or solfataric action, on aluminous rocks, commonly accompanied by kaolinitization and silicification. Kaolinite, halloysite, diaspore, pyrite, gypsum, quartz.

Jarosite-family minerals form part of the isostructural alunite supergroup, which has the general chemical formula AB 3 (TO 4) 2 (OH) 6 (Jambor, 1999; Dutrizac and Jambor, 2000; Smith et al., 2006).

Alunite occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks It is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide deposits. Alunite also is found near volcanic fumaroles.
