The metal extracted by leaching with a cyanide is
- A \( \mathrm{Al} \)
- B \( \mathrm{Ag} \)
- C \( \mathrm{Cu} \)
- D Na
Answer & Solution
Correct Answer
(B) \( \mathrm{Ag} \)
Step-by-step Solution
Detailed explanation
The metal extracted by leaching with a cyanide is Ag. Ores of silica and gold are leached and react with NaCN and air to
convert into \( \mathrm{AgCN} \) which on replacement by zinc give pure metal.
convert into \( \mathrm{AgCN} \) which on replacement by zinc give pure metal.
