KALSILITE
KALSILITE Kalsilite – KAlSiO4 – is a rare tectosilicate, a feldspathoid typical of K-rich and silica-deficient igneous rocks. It has no importance as an ore. It is classified in the Feldspathoid Group, being dimorphic from kaliophilite (trigonal). May contain impurities such as Ca, Na, Fe and Mg. Gelatinizes in concentrated HCl. 1.

KLOCKMANNITE
KLOCKMANNITE Klockmannite – CuSe – is a very rare selenide, characteristic of hydrothermal veins with paragenesis of Se minerals. It may constitute ore, but Se is generally obtained as a by-product in the refining of Pb, Zn and Cu ores. It is the Se analogue of covellite, with which it is isomorphic. It is the […]
