Where is aurichalcite found
Crystallography: Monoclin ic Commonly found in radiating needle crystals. Vitreous luster. Composition, Structure and Associated Minerals: Aurichalcite is found as a secondary mineral in deposits in zinc and copper ores.
While typically found as radiating sprays of needle like crystals, it can also be found in crusts or rarely in more compact columnar, laminated or granular forms. It was first described in , the name means "mountain copper. Associated minerals include: calcite , rosasite, smithsonite , hemimorphite, hydrozincite, limonite , malachite and azurite. Identification and Diagnostics Aurichalcite gives positive tests for both copper and zinc, it is soluble in hydrocloric acid with emission of carbon dioxide.
It is recognized by the presence of both copper and zinc, its color, crystal form and its solubility in acids. Localities Aurichalcite typically occurs in the oxidized zone of copper and zinc deposits in locations where carbonates are present in the wall rocks. It is a very minor ore of zinc and copper. It is valued more highly as a mineral specimen because it makes for attractive, well colored specimens that are highly valued by mineral collectors. Complex Tests.
