Chalcanthite
Chalcanthite is a copper sulfate mineral noted for its electric blue crystals. Chalcanthite is a notable copper ore, but its solubility in water limits its refining potential.
Uses
Chalcanthite can be used as a source of copper, but its commercial viability is significantly limited due to the mineral's water solubility.
Notable Localities
As most Chalcanthite is lab-produced, specimens of the mineral have been recovered at only a few localities. The most famous Chalcanthite locality is the Planet Mine of Arizona, where the mineral occurs as silky curls.
