Q. Metals which can be extracted by smelting process is/are:

Q. Consider the following statements and arrange in the order of true/false as given in the codes.
$S_1$: In the aluminothermite process, aluminium acts as reducing agent.
$S_2$: The process of extraction of gold involves the formation of $\left[Au\right(C{N}_2){]}^{-}$ and $\left[Zn\right(CN{)}_4{]}^{2-}$.
$S_3$: In the extractive metallurgy of zinc, partial fusion of ZnO with coke is called smelting and reduction of ore to the molten metal is called smelting.
