Vedclass · Answer

(D) Pyrometallurgy involves the extraction of metals by heating ores at high temperatures,often with a reducing agent like carbon. $Ag_2S$,$ZnS$,$Cu_2S$,$HgS$,$MnO_2$,and $SnO_2$ are all ores that can be reduced to their respective metals using pyrometallurgical processes (e.g.,roasting followed by reduction with carbon or self-reduction). Since all the given pairs of ores can be converted into their corresponding metals by pyrometallurgy,the correct answer is that none of the pairs are excluded.

Which of the following pair of ores cannot be converted into corresponding metals by pyrometallurgy?
