The correct Answer is:
To solve the question of which option is not an ore of a metal, we will analyze each option provided. ### Step 1: Identify the options Let's denote the options as follows: - A: Zinc Blend (ZnS) - B: Bauxite (Al2O3·2H2O) - C: Malachite (Cu(OH)2·CuCO3) - D: Pig Iron ### Step 2: Analyze each option 1. **Zinc Blend (ZnS)**: - Zinc blend is an ore of zinc. It is composed of zinc sulfide (ZnS), which is mined for the extraction of zinc. - **Conclusion**: This is an ore of a metal. 2. **Bauxite (Al2O3·2H2O)**: - Bauxite is the primary ore of aluminum. It contains aluminum oxide (Al2O3) and is the main source for aluminum extraction. - **Conclusion**: This is an ore of a metal. 3. **Malachite (Cu(OH)2·CuCO3)**: - Malachite is a copper carbonate hydroxide mineral and is an important ore of copper. It is used for the extraction of copper. - **Conclusion**: This is an ore of a metal. 4. **Pig Iron**: - Pig iron is not an ore; it is an intermediate product obtained from smelting iron ore in a blast furnace. It contains a high percentage of carbon and is used to produce cast iron and steel. - **Conclusion**: This is not an ore of a metal. ### Step 3: Final Answer Based on the analysis, the option that is not an ore of a metal is **D: Pig Iron**. ### Summary The correct answer is **D: Pig Iron**, as it is not an ore of any metal but rather a product derived from the smelting of iron ore. ---
