Sulphides ores are converted to oxides before reduction. This is explained on the basis of which of the following?
- A. Sulphides cannot be reduced easily while oxides can be reduced easily.
- B. Sulphides decompose on reduction hence they are fixed converted to oxides.
- C. Sulphide ores have higher melting points than oxides.
- D. Oxides are more stable than sulphides hence easy to reduce.
Step-by-step solution
Sulphide ores are roasted to oxides because oxides are more easily reduced by common reducing agents (e.g., carbon) due to more favorable thermodynamics. Sulphides are generally less reducible, requiring higher temperatures or more complex processes.
