Chalcopyrite Wikipedia

Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t,-k oʊ-/ KAL-ko-PY-ryt) is a copper iron sulfide mineral and the most important ore of copper. It has the chemical formula CuFeS 2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite tarnishes
