Alunite characteristics can provide a good indication of gold ore potential in a high sulfidation epithermal system. Alunite is a potassium sulfate mineral that forms in hydrothermal systems. Sulfates such as alunite and jarosite are common in hydrothermal environments and have distinctive NIR spectra.
Alunite is a hydroxylated aluminium potassium sulfate mineral, formula K Al 3 (S O 4) 2 (OH) 6. It was first observed in the 15th century at Tolfa, near Rome, where it is 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.
Alunite is also known as alumstone and is a source of the chemical known as alum, KAl(SO4)2 - 12H2O.Some alunite has also been used to recover potassium and aluminum. Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called "alunitization".The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals.
Alunite is formed by reworking acid and neutral volcanic rocks that contain orthoclase with hydrothermal sulfuric acid solutions and also by the action of sulfate surface water on aluminiferous rocks. Rocks containing alunite are a source of alum, alumina, potassium salts, and other substances.

Although the alunite itself is used, in large deposits, for the production of alum and similar salts, sometimes gold and other rare metals are associated with areas of alunitization. This type of deposit is known as the epithermal quartz-alunite gold deposit. Gold, pyrite, and enargite are found in vuggy veins and breccias in zones of high ...
In alunite minerals, the B site is filled by Al 3 +, which can form a solid solution with Fe 3 +. In the B site, Fe 3 + preference over Al 3 + increases at higher acidity (pH < 3), lower temperature and/or increased Eh of formation (more oxidizing conditions) (Brophy et al., 1962; Burger et al., 2009).
