What is the sulphide ore of copper?

Sulfide's characteristic trait of bonding a sulfide anion with various metals means that many important metal ores contain sulfide minerals. Some examples of sulfides include galena ( the principle ore mineral for lead and silver), cinnabar (the main ore mineral for mercury), and chalcopyrite (which provides copper).
