Which of the following is NOT an ore of iron? |
Cuprite Haematite Magnetite Siderite |
Cuprite |
The correct answer is option 1. Cuprite. Cuprite \((Cu_2O)\) is a mineral consisting of copper(I) oxide, not iron. It is a source of copper rather than iron. The other options listed are indeed ores of iron: 2. Haematite \((Fe_2O_3)\) is an important iron ore and a primary source of iron. 3. Magnetite \((Fe_3O_4)\) is another significant iron ore, known for its magnetic properties. 4. Siderite \((FeCO_3)\) is also an iron ore, although it is less commonly mined compared to haematite and magnetite. |
