Bornite mineral. Bornite (copper iron sulphide,Cu5FeS4) is a mineral ore and is an important source of copper,a metal used in alloys and for electrical wiring. Bornite is a colourful ornamental mineral,also called peacock ore or peacock copper. The colours are caused by a thin layer of copper oxides,formed upon exposure to air. Because the layers are very thin,they scatter light to produce the shimmering sheen that gives the ore its common name | |
