The ore that contains both iron and copper is:
Updated On: Apr 1, 2026
- malachite
- dolomite
- azurite
- copper pyrites
Show Solution
The Correct Option is D
Solution and Explanation
To determine the ore that contains both iron and copper, we need to analyze the options given:
- Malachite: Malachite is a copper carbonate hydroxide mineral with the formula Cu2(CO3)(OH)2. It primarily contains copper but no iron.
- Dolomite: Dolomite is a calcium magnesium carbonate mineral with the formula CaMg(CO3)2. It contains neither copper nor iron and is often associated with limestone.
- Azurite: Azurite is similar to malachite and is also a copper carbonate mineral with the formula Cu3(CO3)2(OH)2. It contains copper but does not contain iron.
- Copper pyrites: Copper pyrites, also known as chalcopyrite, is a copper iron sulfide mineral with the formula CuFeS2. This mineral contains both copper and iron.
Thus, the correct answer is copper pyrites.
