Options:
Answer:
B
Solution:
The ore mixture contains a non-magnetic amphoteric oxide, which is likely SnO₂ (cassiterite). Magnetic separation removes magnetic impurities. SnO₂ is then roasted to remove volatile impurities, leached to concentrate, and finally carbon-reduced (smelting) to extract Sn.
