Vedclass · Answer

(D) Spiegleisen is an alloy of $Mn$,$Fe$,and $C$. Dow's process uses $Ca(OH)_2$ to precipitate $Mg(OH)_2$ from sea water. Parke's process is used for the desilverization of lead,involving $Ag$. Liquation is used for metals with low melting points like $Sn$ (tin),whereas spelter (impure $Zn$) is purified by distillation or electrolytic refining. Thus,the option $D$ is not correctly matched.
