Vedclass · Answer

(D) Pyrometallurgy involves the extraction of metals by heating ores at high temperatures,often with a reducing agent like carbon or by self-reduction.$Ag_2S$ (Argentite),$ZnS$ (Zinc blende),$Cu_2S$ (Chalcocite),$HgS$ (Cinnabar),$MnO_2$ (Pyrolusite),and $SnO_2$ (Cassiterite) are all ores that can be processed via pyrometallurgical methods.Specifically,$HgS$ and $Cu_2S$ undergo self-reduction,while $MnO_2$ and $SnO_2$ are reduced by carbon,and $Ag_2S$ and $ZnS$ are converted to oxides and then reduced.Since all the listed ores can be converted into their corresponding metals using 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?
