Peacock Ore | WhatAEarth

Peacock Ore (Bornite) is a crystaline variety of Chalcopyrite and they have very similar properties. 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.

Copper - Wikipedia

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
