Copper Matte is extracted from copper pyrites ore by' heating it in blast furnace. The method is based on the principle that: (A) copper has more affinity for oxygen than sulphur at high temperature (B) iron has less affinity for oxygen than sulphur at high temperature (C) sulphur has less affinity for oxygen at high temperature (D) copper has less affinity for oxygen than sulphur at high temperature

2CuFeS2 + O2 → Cu2S + 2FeS + SO2 FeS+(3/2) O2 → FeO + SO2 uparrow FeO + SiO2 → FeSiO3 (Remain Cu2S is called matte)

Q. Copper Matte is extracted from copper pyrites ore by' heating it in blast furnace. The method is based on the principle that:

copper has more affinity for oxygen than sulphur at high temperature

iron has less affinity for oxygen than sulphur at high temperature

sulphur has less affinity for oxygen at high temperature

copper has less affinity for oxygen than sulphur at high temperature

$2 C u F e S_{2} + O_{2} \to C u_{2} S + 2 F e S + S O_{2}$
$F e S + \frac{3}{2} O_{2} \to F e O + S O_{2} ↑$
$F e O + S i O_{2} \to F e S i O_{3}$
(Remain $C u_{2} S$ is called matte)

2CuFeS2​+O2​→Cu2​S+2FeS+SO2​ FeS+23​O2​→FeO+SO2​↑ FeO+SiO2​→FeSiO3​ (Remain Cu2​S is called matte)

$2 C u F e S_{2} + O_{2} \to C u_{2} S + 2 F e S + S O_{2}$
$F e S + \frac{3}{2} O_{2} \to F e O + S O_{2} ↑$
$F e O + S i O_{2} \to F e S i O_{3}$
