Alunite is a hydroxylated aluminium sulfate mineral 3 (S )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 BeudantMagnetite Common Minerals,1125 Ilmenite is a dense, black metallic mineral that, when rubbed across a rough hard surface, exhibits a black streak similar to that of magnetite. As ilmenite is not magnetic, a magnet can be used to distinguish pure samples of the two. Some ilmenite samples appear weakly magnetic, however, due to intergrown magnetite crystals.Alunite Alum Stone Goldia,1013 Alunite is an effective hemostatic and astringent, wounds after stone treatment heal faster. Saline mineral powder is used to prevent foot sweating. Use of alunite The salt stone is used in different vital spheres and branches. Due to its ability to neutralize odors and antibacterial effect, alunite is used in its pure form as a deodorizing agent.

Occurrences and Origin of Alunite, South Jordan Science
Alunite is a very fine hydrous sulfate mineral with hydroxyl in its structure. The formula for pure alunite is KAl 3 (SO 4) 2 (OH) 6. It has a rhombohedral crystal structure. Alunite was recorded for the first time in Jordan by Khoury (1987) in the kaolinite bed of the Kurnub Sandstone Formation of the Lower Cretaceous age.Infrared Spectra of AluniteGroup Minerals Formed on ,719 Alunitegroup minerals [MMIII3(SO4)2(OH)6, space group 3 Rm ] are formed in regions of active volcanism, making them suitable subjects for characterizing mineralization under thermally.Using hyperspectral imagery for identification of ,41 Alternatively, wallrock alteration mineral assemblages can be used to divide epithermal deposits into geothermal and magmatichydrothermal types. The latter is associated with quartz + alunite ± aluminosilicate clays (i.e. pyrophyllite, dickite and kaolinite) assemblages which contain AuAg ± Cu ores (Simmons et al., 2005). These

Discovery of the AcidSulfate Mineral Alunite in Terra
CRISM alunite spectra closely match spectra of lowtemp. terrestrial lacustrine alunites, based on relatively weak vibrationallycoupled absorptions at 1.43, 1.76, 2.21, and 2.32 μm. Given the observed lack of inflow channels, it is likely that the alunite was deposited in a springfed lake that once covered the bottom of the crater.crusher alunite stones,Alunite Stones Crusher Alunite Mineral Processing Raw alunite stone are evenly fed into the jaw crusher by vibrating feeder for major crushing .
