The absence of xanthate on the mineral surface was confirmed by Fourier transform infrared spectroscopy. © Thomas Witzke / Abraxas-Verlag, Mouse Also, the Mid-Atlantic-ridge isocubanite may transform to chalcopyrite and UM1994-22-S:CuFe (Cu 1-x Fe 3+x S 4 (Wintenberger et al., 1994). Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS 2), with pyrite (FeS 2), but the two can be distinguished by their relative hardness and chalcopyrite’s iridescent tarnish. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. Pyrite is the harder of the two and cannot be easily scratched by a nail, unlike chalcopyrite. Brass yellow, may have iridescent purplish tarnish. Further Reading. _uacct = "UA-3067463-1"; Comments: Well-formed crystals of chalcopyrite and quartz. Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow.
