Extraction of silver is achieved by initial complexation of the ore (Argentite) with X followed by reduction with Y. X and Y respectively are

A

`CN^(-)` and Zn

B

`CN^(-)` and Cu

C

`Cl^(-)` and Zn

D

`Br^(-)` and Zn

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(" Complexation step"),(Ag_2S + CN rarr [Ag(CN_2)]^(-) + S^(-2)),(" "darr + "Zn Reduction step"),(" "[Zn(CN)_4]^(-2) + Ag):}`
