The ore which is concentrated by leaching
- A \(\mathrm{PbS}\)
- B \(\mathrm{Al}_2 \mathrm{O}_3 \cdot 2 \mathrm{H}_2 \mathrm{O}\)
- C \(\mathrm{SnO}_2\)
- D \(\mathrm{Fe}_2 \mathrm{O}_3\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Al}_2 \mathrm{O}_3 \cdot 2 \mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
Leaching is a process in which powdered ore is treated with certain reagents, which dissolves the ore leaving behind impurities in undissolved form. Aluminium ore is concentrated by this method, bauxite \(\left(\mathrm{Al}_2 \mathrm{O}_3 \cdot 2 \mathrm{H}_2 \mathrm{O}\right)\)…
