Chalcocite: Properties and Occurrences - Assignment Point

Chalcocite: Properties and Occurrences. Chalcocite, copper (I) sulfide (Cu 2 S), is an important copper ore mineral. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur.

Upon exposure to moisture, bornite tarnishes to a purplish iridescence, for which reason it is commonly called peacock ore. Hardness is 3, streak pale grayish black. Bornite occurs with chalcopyrite and chalcocite, both more important as ores, in copper deposits that typically form as zones of contact metamorphism (see metamorphic rock) and as sulfide ore veins.

Bornite Mineral | Physical - Optical Properties, Occurrence, Uses

Bornite is also known as "purple copper ore" and "variegated copper ore." Bornite crystals are uncommon. Although they exhibit orthorhombic symmetry, crystals, when found, are cubic, octahedral, or dodecahedral, often with curved or rough faces. Bornite is frequently compact, granular, or massive and alters readily to chalcocite and other copper minerals upon weathering. It forms mainly in hydrothermal copper ore deposits with minerals such as chalcopyrite, pyrite marcasite, and ...
