The study of alunite supergroup minerals (alunite, jarosite, and aluminum-phosphate-sulfate (APS) minerals) that are part of the acidic alteration assemblages, can help to better constrain the hydrothermal and supergene alteration events, as these minerals record information about the precipitation environment and the nature and …
Stage I alunite is chemically heterogeneous and commonly contains turbid core of partially altered woodhouseite–svanbergite, crandallite, and florencite. Its Na/K value is characteristically high (up to 0.4). In the intermediate and sericite zone, alunite is rare. Stage II alunite is fine-grained and has a characteristic pseudomorphic morphology.

Alum is produced as aluminum sulfate by treating bauxite with sulfuric acid to yield alum cake or by treating the bauxite with caustic soda to yield papermaker's alum. Other industrial alums are potash alum, ammonium alum, sodium alum, and chrome alum (potassium chromium sulfate). Major uses of alum are as an astringent, styptic, and emetic.
alum, any of a group of hydrated double salts, usually consisting of aluminum sulfate, water of hydration, and the sulfate of another element. A whole series of hydrated double salts results from the hydration of the sulfate of a singly charged cation (e.g., K +) and the sulfate of any one of a number of triply charged cations (e.g., Al 3+ ).

Alunite, or alumstone, is a mineral that was first observed in the 15th century in Monti della Tolfa, north to Rome, where it was mined for the manufacture of alum.First called aluminilite by J.C. Delametherie in 1707, this name was contracted by François Beudant in 1824 to alunite.. Distinct crystals of alunite are rarely found in cavities in the massive material.
Introduction. Alunite is a sulfate mineral that was first observed in the 15th century at Tolfa, north of Rome. Historically, extensive deposits were mined in Tuscany, Hungary and Australia, but also in different localities in the United States, the most studied being that in alunite near Marysvale, Utah [1], [2].Alunite was first mined for alum or as …
The acid processing route of primary alunite has several distinct advantages over the alkali processing route: (1) an Al–Si separation process is not needed; (2) potassium and aluminum salts are easily crystallized from an acidic solution for formation of alum; and (3) the crystallization mother liquor of alum can be recycled (Froisland et al ...
Alunite; Alunite Named after the Latin word for "alum", this mineral is also called "alumstone." It was discovered in Latium, Italy, in 1824 and is formed by sulfuric acid solutions acting on rocks rich in potash feldspar. In Marysvale, Utah, it has been mined and treated to recover potassium and aluminum. ...

Occurrence of Alunite and Useful Mineral Association. Alunite is formed between 15°C (59°F) and 400°C (752°F) by the action of sulfate generated from pyrite or solfataric action on aluminous rocks, along with silicification and kaolinitization. It is closely associated with quartz, gypsum, pyrite, diaspore, halloysite, and kaolinite.
