Chalcopyrite mineral information and data - dakotamatrix

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.

Chalcopyrite Leaching - Metallurgist & Mineral Processing ...

Chalcopyrite Leaching. The difficulty of leaching chalcopyrite under ambient conditions is generally considered to be surface passivation either from reaction products or adsorbed surface species layers, such as jarosite formation. The sulphur-rich layer presents a diffusion barrier to the continued dissolution reaction for copper.
