Alunite - chemeurope

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.

Alunite - an overview | ScienceDirect Topics

Alunite is one of the minerals of the jarosite group and contains approximately 50% SiO 2. Characteristics of alunite can be found in the review by Dill (2001). However, untreated alunite does not have good adsorbent properties (Özacar and Sengil, 2003). After a suitable process, alunite-type layered compounds are useful as adsorbents for ...
