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 $[A u (C N_{2})]^{-}$ and $[Z n (CN)_{4}]^{2 -}$ .
$S_{3}$ : 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.
