Chalcopyrite ( / ˌ k #230; l k ə ˈ p aɪ r aɪ t, k oʊ / KAL ko PY ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS 2.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 oxidises
Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.
