- tin from $SnO_2$
- iron from $Fe_2O_3$
- aluminium from $Al_2O_3$
- magnesium from $MgCO_3 . CaCO_3$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Al has greater affinity for oxygen, hence oxide is not reduced by carbon. MgO and CaO (formed in the calcination from carbonates) are stable species and not reduced by carbon.
During Smelting $SnO_2+C_2\xrightarrow{1300^{\circ}C}Sn+CO$
$2Fe_2O_3+3C\xrightarrow{\Delta}4Fe+3CO_2$
During Smelting $SnO_2+C_2\xrightarrow{1300^{\circ}C}Sn+CO$
$2Fe_2O_3+3C\xrightarrow{\Delta}4Fe+3CO_2$

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
