Vedclass · Answer

(C) Calcination is a process of heating an ore in a limited supply of air or in the absence of air.$(1)$ It removes moisture from the ore,which is $True$.$(2)$ It decomposes carbonates into oxides and carbon dioxide (e.g.,$CaCO_3 \rightarrow CaO + CO_2$),which is $True$.$(3)$ It removes volatile impurities (like organic matter or non-metallic impurities),which is $True$.Therefore,all statements are $True$. The correct option is $TTT$.

List-$I$	List-$II$
$(I)$ Calcination	$a. Fe_2O_3 \cdot nH_2O \rightarrow Fe_2O_3 + nH_2O$
$(II)$ Roasting	$b. 2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$
$(III)$ Flux	$c. SiO_2 + FeO \rightarrow FeSiO_3$
$(IV)$ Thermite	$d. Cr_2O_3 + 2Al \rightarrow Al_2O_3 + 2Cr$

In metallurgy,select the correct option using $T$ (True) or $F$ (False) for the statements given regarding calcination:
$(1)$ It is used to remove moisture.
$(2)$ It is used to decompose carbonates.
$(3)$ It is used to remove volatile impurities.
