____________________ flux is used for the extraction of metal from its self fluxing ores?
Correct answer: A. No
- A. No
- B. Acid
- C. Basic
- D. Neutral
Explanation
A self-fluxing ore already contains gangue constituents capable of forming a fusible slag, so adding an external flux is unnecessary. Acid or basic flux is required only when the ore does not provide this function itself.
