Question

Given below are two statements, one is labelled as Statement-1 and the other is labelled as Statement-2: Statement-1: Sulphides are converted into oxide first. Statement-2: Because oxides can be reduced easily. In the light of the above statements, choose the correct answer from the options given below

• A. Only 1st is correct
• B. Only 2nd is correct
• C. Both are correct
• D. Both are incorrect

Answer 1

The Correct Option is C

To address this question, we need to evaluate the correctness of both Statement-1 and Statement-2 based on our understanding of the metallurgy process:

1. Statement-1: Sulphides are converted into oxide first.
   • This is a factual statement in the context of metallurgy. Sulphide ores are often roasted in the air to convert them into oxides. This is because metal oxides are generally more amenable to reduction processes compared to sulphides.
2. Statement-2: Because oxides can be reduced easily.
   • This statement provides the reasoning behind the conversion of sulphides to oxides. Oxides can be reduced using common reducing agents like carbon, which is a standard step in metal extraction. Therefore, this statement is also correct.

The linkage between these statements is significant in the extraction of metals. Initially, sulphide ores are roasted to form oxides because it is energetically more favorable to convert oxides into pure metal during the reduction stage. Hence, the process ensures efficient extraction, justifying the link between sulphides and oxides.

Given this reasoning, both statements are correct and provide consistent reasoning for the process of converting sulphides into oxides in metallurgy.

Conclusion: The correct option is "Both are correct".
