Chalcopyrite, a mineral of copper iron sulfide, uses the tetragonal system to crystallize.. It comes in a golden yellow to a brassy color. Its splash is indicative as black, tinged with green. On a continuous exposure to air, it yields a variety of sulfates, oxides and hydroxides. Related copper minerals are the sulfides like Covellite (CuS), Bornite (Cu5FeS4), Digenite (Cu9S5) Chalcocite (Cu2S), and Carbonates like Malachite and Azurite and they are rarely known to oxidize with minerals like Cuprite (Cu2O). It seldom occurs along with native copper.
Derivation of Name
The Chalcopyrite mineral gets its name from the Greek word “chalkos”, meaning “copper" and hence "Copper Pyrite."
This is a chief ore of copper, occurring in a various kinds of ores. It may be found in coal seams coupled with pyrite nodules and as disseminations in carbonate sedimentary rocks.
This stone possesses strange power that brings in a strong spiritual energy. Once you start feeling the vibration caused, it could be a great experience to let this energy embrace you in attaining a state of mind that can help you realize deeper spiritual understanding. Chalcopyrite is a superb stone for practicing meditation and can be pretty powerful when used at the position of the third eye, which is the highest chakra of the physical body, known as the crown chakra. It clears energy blockages of the said chakra as it cleanses and activates the same.
Chalcopyrite occurs in great quantities, just as in Timmins, Ontario. It also appears in disseminations and veins in the deposits of copper in Broken Hills, the Andes and the American Cordillera. The purest form of chalcopyrite ever found, was in Canada in the deposits of huge quantities at the South extremes of the Temagami greenstone belt, from where superior quality copper was extracted from the Copperfield Mines. Besides, Chalcopyrite also exists in South Australia in the deposits of Cu-Au-U in Supergiant Olympic Dam deposits
This beautiful mineral usually has good crystals. It is easily available and its superior samples are affordable. Natural chalcopyrite does not have any solid solution series with any other sulfide minerals. Though its crystal structure is similar to sphalerite, there is partial replacement of Zinc with Copper. Though in its natural form it is sparkling, natural colors like strong purples and blues generally get formed on getting treated with acids.
It occurs in a golden yellow color that generally resembles Gold. But its physical properties are quite different from Gold and can be distinguished easily.
