BROCHANTITE

Brochantite, named after the French mineralogist Brochant de Villiers, is a basic sulphate of copper, occurring in emerald-green crystals. Brochantite was first identified at a mine near Sverdlovsk in the Ural mountains of Russia, and confirmed as a distinct mineral in 1824. Brochantite is an ore of copper, but a minor one.
