MatchitemsofColumn Iwiththeitems ofColumnII and assignthecorrect code : {:(, "Column I",,,"Column II"),((A), "Cyanide process",,(1),"Ultrapure Ge"), ((B),"FrothFloatation Process",,(2), "Dressing of ZnS"), ((C ), "Electrolytic reduction",,(3), "Extraction of Al"), ((D), "Zone refining",,(4), "Extraction of Au"), (,,,(5), "Purification of Ni"):}
Answer» A(4) `"" `B(2) `""`C(3)`""`D(1) A(2) `"" `B(3) `""`C(1)`""`D(5) A(1) `"" `B(2) `""`C(3)`""`D(4) A(3) `"" `B(4) `""`C(5)`""`D(1) Solution :Explanation. Cyanideprocess is usedfor extractionof Au. FROTH Floatatio PROCESS isusedforconcentration of sulphideores. Electrolyticreductionis usedforextractionof Al.Zonerefiningisusedtoobtainultrapure GE.
