Calcination is a process in which ore is heated mainly in the absence of air whereas roasting is a process in which ore is heated in the presence of air.

2 C u_{2} S + 3 O_{2} Δ 2 C u_{2} O + 2 C O_{2}

(Roasting)

Q. The reaction that does not define calcination is

$Z n C O_{3} ⟶ Δ Z n O + C O_{2}$

$F e_{2} O_{3} \cdot X H_{2} O ⟶ Δ F e_{2} O_{3} + X H_{2} O$

$C a C O_{3} \cdot M g C O_{3} ⟶ Δ C a O + M g O + 2 C O_{2}$

$2 C u_{2} S + 3 O_{2} ⟶ Δ 2 C u_{2} O + 2 S O_{2}$

Calcination is a process in which ore is heated mainly in the absence of air whereas roasting is a process in which ore is heated in the presence of air.

Q. The reaction that does not define calcination is

ZnCO3​⟶Δ​ZnO+CO2​

Fe2​O3​⋅XH2​O⟶Δ​Fe2​O3​+XH2​O

CaCO3​⋅MgCO3​⟶Δ​CaO+MgO+2CO2​

2Cu2​S+3O2​⟶Δ​2Cu2​O+2SO2​

Calcination is a process in which ore is heated mainly in the absence of air whereas roasting is a process in which ore is heated in the presence of air. 2Cu2​S+3O2​Δ​2Cu2​O+2CO2​ (Roasting)

$Z n C O_{3} ⟶ Δ Z n O + C O_{2}$

$F e_{2} O_{3} \cdot X H_{2} O ⟶ Δ F e_{2} O_{3} + X H_{2} O$

$C a C O_{3} \cdot M g C O_{3} ⟶ Δ C a O + M g O + 2 C O_{2}$

$2 C u_{2} S + 3 O_{2} ⟶ Δ 2 C u_{2} O + 2 S O_{2}$

Calcination is a process in which ore is heated mainly in the absence of air whereas roasting is a process in which ore is heated in the presence of air.
