Vedclass · Answer

(A) Refining is the process of purifying crude metal.$A$. Liquation is a refining method used for metals with low melting points (e.g.,$Sn$).$B$. Calcination is a process of concentration of ore (converting carbonate ore to oxide),not refining.$C$. Electrolysis is a common refining method (e.g.,for $Cu$,$Zn$).$D$. Leaching is a process of concentration of ore (chemical extraction),not refining.$E$. Distillation is a refining method used for volatile metals (e.g.,$Zn$,$Hg$).Therefore,$B$ (Calcination) and $D$ (Leaching) are not used for refining.
