(B) The cupellation process is a refining method used to separate noble metals like $Ag$ (silver) and $Au$ (gold) from base metals like $Pb$ (lead). In this process,the impure metal is heated in a cupel (a shallow porous vessel) in an oxidizing atmosphere. The base metals oxidize to form their oxides,which are absorbed by the porous cupel,while the noble metal remains behind in the metallic state.
