Alunite
Alunite is a potassium aluminum sulfate hydroxide mineral with the chemical formula KAl3(SO4)2(OH)6. It crystallizes in the trigonal crystal system and is classified as a sulfate mineral in the Strunz system (7.BC.10) and as a sulfatite in the Dana classification (30.2.4.1). Alunite typically exhibits a white streak and a vitreous to dull luster. It is usually found in white, gray, or yellowish colors. The mineral has a hardness of approximately 3.5 to 4 on the Mohs scale and a relatively high density. Alunite is commonly associated with hydrothermal and volcanic environments and belongs to the sulfate mineral group.

Etymology
The name 'alunite' is derived from 'alum,' a group of minerals and salts with similar chemical properties. This naming reflects its historical association with alum compounds used in various applications.
Geological genesis
Alunite typically forms in hydrothermal and volcanic environments, often associated with the alteration of aluminum-rich rocks. It is commonly found in association with other sulfate and hydroxide minerals, and its formation is linked to the interaction of acidic fluids with surrounding rock.
