Known Copper Sulfides
The naturally occurring mineral binary compounds of copper and sulfur are listed below. There are probably more yet to be discovered, for example investigations of "blaubleibender covellite" (blue remaining covellite) formed by natural leaching of covellite (CuS) indicate that there are other metastable Cu-S phases still to be fully characterised.
- CuS2, villamaninite or (Cu,Ni,Co,Fe)S2
- CuS, covellite, copper monosulfide
- Cu9S8 (Cu1.12S), yarrowite
- Cu39S28 (Cu1.39S) spionkopite
- Cu8S5 (Cu1.6S), geerite
- Cu7S4 (Cu1.75S), anilite
- Cu9S5 (Cu1.8S), digenite
- Cu31S16 (Cu1.96S), djurleite
- Cu2S, chalcocite

Famous quotes containing the word copper:
“He had put, within his reach,
A box of counters and a red-veined stone,
A piece of glass abraded by the beach,
And six or seven shells,
A bottle with bluebells,
And two French copper coins, ranged there with careful art,”
—Coventry Kersey Dighton Patmore (1823–1896)
