Vedclass · Answer

(B) The ore cassiterite is $SnO_2$. The extraction process involves the following steps:$1$. Concentration of the ore by gravity separation.$2$. Roasting to remove sulfur and arsenic impurities.$3$. Carbon reduction of the oxide ore: $SnO_2 + 2C 	o Sn + 2CO$.$4$. Refining of the metal to remove impurities like $Fe$,$W$,and $Cu$.Since cassiterite is an oxide ore,it does not undergo self-reduction,which is characteristic of sulfide ores like $Cu_2S$ or $PbS$.

Extraction of metal from the ore cassiterite does not involve:
