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.

As the zone begins to come upon the quartz alunite zone, montmorillonite dies out slowly. Within the montmorillonite subzone alterations of plagioclase is found and sometimes altered to illite. Biotite is also found in this subzone and altered to illite …

On Earth, large deposits of alunite and jarosite are most commonly found in volcanic acid-sulfate systems—where they usually precipitate by alteration of feldspar and other silicates—or in acid mine drainages such as Rio Tinto, where they precipitate by oxidation of pyrite and other metal sulfide minerals in massive sulfide deposits [20,31 ...

Where are metal deposits found? Metallic ores occur in every kind of rock and some varieties of soil. The metallic minerals are concentrated into rich masses by igneous, hydrothermal, or erosional/weathering processes. Metals such as chromium, platinum, nickel, copper, and iron can precipitate as sulfide minerals in a cooling body of magma.

alunite veins are formed by hydrothermal activity. Alunite has also been found in metamorphic rocks. Aqueous alteration of alunite in the presence of silica leads to the formation of kaolinite, muscovite or K-feldspar. Alunite dissolution in low-silica environments forms böhmite, γ-AlOOH. Jarosite is a common weathering product of

• Alunite has a specific gravity of 2.82, slightly higher than quartz and clays, and so a greater heft commonly is a good clue to presence of high alunite content in the rock. • Vein alunite commonly is flesh-pink, but color is a poor criterion in identifying alunitized rocks, wich may be off-white, gray, yellowish, brownish, or pinkish ...

Alums occur naturally in various minerals. Potassium alum, for example, is found in the minerals kalinite, alunite, and leucite, which can be treated with sulfuric acid to obtain crystals of the alum. Most alums have an astringent and acid taste. They are colourless, odourless, and exist as a white crystalline powder.
