Question

What happens when Copper matte is charged into silica lined converter and hot air blast is blown? 

Answer 1

 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 
\[\ce{2Cu2O + Cu2S→ \underset{(Blister Cu)}{6Cu + SO2}}\]
