Vedclass · Answer

(D) The extraction of silver from argentite $(Ag_2S)$ involves the Mac-Arthur Forrest cyanide process.First,the ore is treated with a dilute solution of $NaCN$ to form a soluble complex:$Ag_2S + 4NaCN 	o 2Na[Ag(CN)_2] + Na_2S$Then,the silver is displaced from the complex by adding a more reactive metal like zinc:$2Na[Ag(CN)_2] + Zn 	o Na_2[Zn(CN)_4] + 2Ag$

From argentite $(Ag_2S)$ ore,the method used in obtaining metallic silver is:
