Question
What happens when Copper matte is charged into silica lined converter and hot air blast is blown?
Solution
When copper matte is charged into silica line converter and hot air is blown it convert remaining FeS, FeO, And Cu2S/Cu2O to metallic copper
2FeS + 3O2 → 2FeO + 2SO2
FeS + SiO2 → FeSiO3
2Cu2S + 3O2 → 2Cu2O + 2SO2
\[\ce{2Cu2O + Cu2S→ \underset{(Blister Cu)}{6Cu + SO2}}\]
