Solution

The correct option is A Mac Arthur- Forrest method
Cyanide process is used for extraction of Ag which is also called Mc-Arthur forest process.Reactions occurs in extraction of silver -

$A g_{2} S + 4 N a C N \to 2 N a [A g (C N)_{2}] + N a_{2} S$ (reversible reaction)

$4 N a_{2} S + 5 O_{2} + H_{2} O \to 2 N a_{2} S O_{4} + 4 N a O H + 2 S$

and $2 N a [A g (C N)_{2}] + Z n \to N a_{2} [Z n (C N)_{4}] + 2 A g$
