 Technical specifications:

Bornite is a copper iron sulfide mineral commonly found in hydrothermal veins, contact metamorphic rocks and in the enriched zone of sulfide copper deposits. It is a common ore of copper and is easily recognized because it tarnishes to iridescent shades of blue, purple, green and yellow. It alters readily upon weathering to chalcocite and other copper minerals. It is often mined as an ore of copper.
Typical occurrences are found in Mount Lyell, Tasmania; Chile; Peru; and Butte, Mont., U.S. |
