Vedclass · Answer

(D) Roasting is a process of heating a sulfide ore in a regular supply of air in a furnace at a temperature below the melting point of the metal. During roasting: $1$. Sulfide ores are converted into oxides (e.g.,$2ZnS + 3O_2 \rightarrow 2ZnO + 2SO_2$). $2$. Volatile impurities like arsenic $(As_2O_3)$ and sulfur $(SO_2)$ are removed as gases. Therefore,both statement $A$ and statement $C$ are correct. Since the question asks for the correct statement and $D$ is 'All of the above',$D$ is the most appropriate answer.
