  • Alunite Wikipedia

    Alunite is a hydroxylated aluminium potassium sulfate mineral, formula KAl3(SO4)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 crystals morphologically are rhombohedra with interfacial angles of 90° 50', causing them to res

  • Alunite mineral Britannica

    Alunite, also called Alum Stone, a widespread rock-forming sulfate mineral that occupies pockets or seams in volcanic rocks such as rhyolites, trachytes, and andesites, where it presumably formed through their stone reaction with escaping sulfurous vapours. It has been used as a source of potash (during World War I) and as a source of alumina (during World War II); in Europe it was once

    Alunite is also known as alumstone and is a source of the stone 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.
