noun a mineral consisting of a sulfide of copper and iron that is a common ore of copper
Bornite is a sulfide mineral with a chemical composition of Cu5FeS4. It is commonly found in hydrothermal veins associated with copper deposits.
Bornite is an important ore of copper and is often processed to extract copper metal. It is used in various industrial applications, including electrical wiring and plumbing.
In mineralogy, bornite is known for its iridescent tarnish, which gives it the nickname 'peacock ore'. It is often used as a collector's mineral due to its striking appearance.
Although bornite is not commonly used as a gemstone due to its low hardness, it is sometimes cut and polished for ornamental purposes. It can display vibrant colors when polished.
Bornite crystallizes in the orthorhombic system and typically forms pseudocubic crystals with a metallic luster. It exhibits distinct cleavage and twinning patterns.
Bornite is used by geologists as an indicator mineral for copper deposits, as it is commonly associated with copper ores.
Metallurgists use bornite in the process of extracting copper from its ores, as it is one of the main copper minerals that can be found in nature.
Mineralogists study bornite as a mineral specimen to understand its crystal structure, properties, and formation conditions.
