Rosasite is a carbonate mineral with minor potential for use as a zinc and copper ore. Chemically it is a copper zinc carbonate hydroxide with a copper to zinc ratio of 3:2 occurring in the secondary oxidation zone of copper-zinc deposits. It was originally discovered in 1908 in the Rosas mine in Sardinia Italy and is named after the location. Fibrous blue-green rosasite crystals are usually found in globular aggregates often associated with red limonite and other colourful minerals.
