During the deep-dive extraction of Copper, the "copper matte" obtained from the reverberatory furnac — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Bessemerisation involves blowing air and sand. The $FeS$ impurity oxidizes first to $FeO$ and is removed as slag ($FeSiO_3$). A portion of $Cu_2S$ oxidizes to $Cu_2O$. Before it can fully oxidize to $CuSO_4$ (C is incorrect), the $Cu_2O$ reacts with the remaining $Cu_2S$ via self-reduction to form Blister Copper.
