The correct Answer is:
To determine which of the given options is an oxide ore, we will analyze each one based on their chemical formulas and classifications. ### Step 1: Analyze Zinc Blend - **Chemical Formula**: ZnS - **Classification**: This is a sulfide ore because it contains sulfur (S) combined with zinc (Zn). ### Step 2: Analyze Malachite - **Chemical Formula**: Cu2CO3(OH)2 - **Classification**: This is a carbonate ore as it contains carbonate (CO3) and hydroxide (OH) along with copper (Cu). ### Step 3: Analyze Feldspar - **Chemical Formula**: KAlSi3O8 or NaAlSi3O8 - **Classification**: Feldspar is classified as a silicate mineral and does not contain oxide in its formula. It consists of aluminum (Al), silicon (Si), and alkali metals (K or Na). ### Step 4: Analyze Bauxite - **Chemical Formula**: Al2O3 - **Classification**: This is an oxide ore because it consists of aluminum (Al) combined with oxygen (O), making it an aluminum oxide. ### Conclusion After analyzing all the given options, we conclude that the only oxide ore among them is **Bauxite (Al2O3)**. ### Final Answer The oxide ore is **Bauxite (Al2O3)**. ---
