Chalcopyrite

Chalcopyrite is one of the sulphide minerals referred to as “Fool’s Gold”, and is often confused with pyrite. Although it is not as rich in copper as some minerals, chalcopyrite is the major ore of copper due to large quantities and widespread distribution. Named from the Greek words for “copper,” chalkos, and for “fire,” pyr, likely in reference to the color of the mineral as well as its copper content. While similar to pyrite, Chalcopyrite is distinguished physically and visually as being softer and a brighter yellow with a green hue when wet. Chalcopyrite is extremely common and widespread. Outstanding localities for Chalcopyrite include in the United States, Mexico, Peru, Canada, Slovakia, the Czech Republic, Germany, Norway, Japan, and South Africa.
