The metal which is extracted by oxidation and subsequent reduction from its ore is :

Accepted Answer

Ag is first extracted by oxidation and then the subsequent reduction is carried out to obtain

\begin{aligned} \begin{array}{r} 4 Ag + 8 NaCN + 2 H_{2} O + O_{2} \end{array} \overset{Oxidation}{⟶} 4 Na [Ag (CN)_{2}] + 4 NaOH \\ 2 Na [Ag (CN)_{2}] + Zn \overset{reduction}{⟶} {Na}_{2} [Zn (CN)_{4}] + 2 Ag \end{aligned}
