Copper in the Roman Empire UNRV

Miners today are mining brassy yellow copper "sulfide" minerals such as chalcopyrite. The sulfides were more difficult to smelt than the green and blue copper "oxide" minerals used by the Sumerians. The Romans were fortunate that the oxide ore was closer to the surface, and that there was a great deal of it.

University of Minnesota's Mineral Pages Chalcopyrite

Chalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. 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. Pyrite is the harder of the two and cannot be easily scratched by a nail, unlike chalcopyrite.
