Question

Which of the following ore contains both copper and iron?

• A. Cuprite
• B. Chalcocite
• C. Chalcopyrite
• D. Malachite

Answer 1

Answer: (C)

Chalcopyrite

Cuprite is an oxide mineral composed of copper(I) oxide $C{u}_{2}O$

Chalcocite, copper(I) sulfide ($C{u}_{2}S$), is an important copper ore mineral.

ChalcopyriteIt has the chemical formula $CuFe{S}_2$.

Malachite is a copper carbonate hydroxide mineral, with the formula $C{u}_{2}C{O}_3(OH{)}_3$

So Chalcopyriteore contains both Copper and Iron.

Hence option C is correct.
