Show Solution
The Correct Option isA
Solution and Explanation
To address this question, we need to analyze each statement individually and determine if they are both correct, incorrect, or if one is correct and the other is incorrect.
Statement I: In the metallurgy process, sulphide ore is converted to oxide before reduction.
This statement is correct. In metallurgy, particularly in the processing of sulphide ores, it is a common practice to first convert the sulphide to an oxide before reduction. This is usually done via roasting, where the ore is heated in the presence of oxygen to convert the sulphide (S2-) into an oxide. For example, roasting zinc sulfide (ZnS) in air converts it to zinc oxide (ZnO):
2 \text{ZnS} + 3 \text{O}_2 \rightarrow 2 \text{ZnO} + 2 \text{SO}_2 \uparrow
Statement II: Oxide ores in general are easier to reduce.
This statement is also correct. Oxide ores are often preferred for reductions because they can be reduced directly using reducing agents like carbon, carbon monoxide, or hydrogen. The reduction process for oxide ores is typically less energy-intensive and simpler compared to the direct reduction of sulphide or other complex ores.
Both statements are correct and align with the principles of metallurgy and reduction techniques. Given this analysis, the most appropriate answer is:
