15.12.2019· Wolframite ore is separated from tinstone ore by the process of (a) Roasting (b) Electromagnetic (c) Smelting (d) Calcination. SOL: (b) Wolframite ore FeWO4 is present in tin stone as impurities and it has same mass per unit volume as that of tin stone. So it is separated by electromagnetic separator because wolframite is magnetic in nature hence it gets attracted by magnet while tin stone
Solution : Wolframite ore \ [ [FeW { {O}_ {4}}]\] is present in tin stone as impurities and it has same mass per unit volume as that of tin stone. So it is separated by electromagnetic separator because wolframite is magnetic in nature hence it gets attracted by magnet while tin stone
