Kalinite is a fibrous monoclinic type of alum distinct from isometric potassium alum[5], named in 1868.
Its name comes from Kalium (derived from Arabic: القَلْيَه‎ al-qalyah “plant ashes”) which is the Latin name for potassium, hence its chemical symbol, "K".
A proposal to discredit kalinite as a mineral species has been submitted to the International Mineralogical Association[4], but it is currently (March 2010) on the list of approved minerals[6].


Kalinite is a rare secondary mineral observed in the oxidized zone of mineral deposits, as efflorescence on alum slates, in caves, and as a volcanic sublimate[7]. It is associated with jarosite, KFe3+3(SO4)2(OH)6, and cuprian melanterite (pisanite), (Fe2+,Cu2+)SO4·7H2O, at Quetena, Chile[[8].
