Properties of Chalcopyrite. The following are the key properties of Chalcopyrite: Equant, tetrahedral-shaped crystals, may be modified by scalenohedral faces, to as large as 10cm. Sphenoidal faces {112} typically large, dull in luster, and striated k [110]; {112} faces are small and bright. Commonly massive, compact; can be botryoidal.

Chalcopyrite, as the name suggests, is somewhat similar to the most common sulfide mineral pyrite but the difference becomes obvious when we have a chance to see them next to each other: Greenish copper-bearing minerals on the wall of an abandoned copper mine in Norway. These minerals are alteration products of chalcopyrite. Dragset, Norway.

The minerals commonly associated with chalcopyrite include pyrite, bornite, chalcocite, galena, and sphalerite. Uses Area. The most important use of chalcopyrite is an ore of copper for five thousand years. Some chalcopyrite ores consist of some amount of zinc substituting for iron. Some chalcopyrite ores consist of sufficient mining silver or ...

Chalcopyrite Chemical. Chalcopyrite is known as the copper mineral with its structurally face-centred tetragonal lattice. The most important and major source of copper metal is the widely spread copper-iron sulphide mineral with chalcopyrite chemical formula of (CuFeS 2). The specific gravity ranges between 4.1 to 4.3.

Chalcopyrite is the dominant Cu ore mineral in most porphyry deposits, which make up an estimated 70% of the global Cu resource (Singer, 2017), and is also widespread in other important deposit types. As near-surface Cu oxide resources are mined out, chalcopyrite will increase as a fraction of the future global Cu supply.
