Question

Choose the correct sequence for extraction of metal from its ore
i) Concentration of ore.
ii) Reduction of metallic oxides
iii) Conversion of the ore into its oxide
iv) Refining of impure metal

• A. $i\to iii\to iv\to ii$
• B. $iv\to i\to iii\to ii$
• C. $i\to ii\to iii\to iv$
• D. $i\to iii\to ii\to iv$

Answer 1

The correct option is D $i\to iii\to ii\to iv$

First, the ore is concentrated by removal of impurities based on physical properties and the resulting concentrated ore is converted to its oxide. Further, the metal oxide is reduced to metal and then it is refined to obtain the pure metal.
