The process by which any metal is extracted from its ore is AreductionBelectrolysisCdisplacementDdecomposition

Which reducing agent can be used in the extraction of metals placed at the top of the reactivityseries?

he method of extraction of crude metal from concentrated ore involves the reduction. Among the following the incorrect method for the given metal isCarbon reduction method is used for Cu, Fe and zinc with the thermodynamic feasibility in the order of Zn < Fe < CuThe Hall-Heroult process of electrolysis involves overall reaction,2Al2O3 + 3C → 4 Al + 3CO2Low grade copper ores are reduced by scrap zinc or H2The extraction of gold and silver by displacement method involves zinc as reducing agent
