copper ore chalcocite
Chalcocite: The mineral Chalcocite information and pictures
Chalcocite is an important copper ore. It has a high copper content and the process of extracting the copper from the sulfur in Chalcocite is relatively easily. Chalcocite is also an important collector's mineral, and good crystals command very high prices. In Europe, a classic Chalcocite locality is Cornwall, England.
