/ˈbɔrˌnaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Born , -ite suffix¹.

Etymology: < the name of Ignatius von Born (1742–91), Austrian mineralogist + -ite suffix¹: compare quot. 1811.

Mineralogy.

A reddish-brown, copper-containing mineral with an iridescent purple surface, typically found in masses, less commonly as approximately cubic or dodecahedral crystals.Bornite is a sulphide of copper and iron, Cu₅FeS₄. Crystal system: orthorhombic.

Also called erubescite. Cf. peacock copper n. at peacock n. and adj. Compounds 2, purple copper ore n. at purple adj. and n. Compounds 1b(c).
