Explanation:
The extraction of copper from chalcopyrite involves several steps, including the reactions that occur in the Bessemer converter. Let's examine each option and determine which reaction does not occur in the Bessemer converter.
Option A: 1 CuFeS2 + O2 → Cu2S + 2FeS + SO2
This reaction represents the roasting of chalcopyrite, where copper sulfide (CuFeS2) reacts with oxygen (O2) to form copper(I) sulfide (Cu2S), iron sulfide (FeS), and sulfur dioxide (SO2). This reaction occurs during the roasting step of the extraction process in the Bessemer converter.
Option B: FeO + SiO2 → FeSiO3
This reaction represents the formation of iron silicate (FeSiO3) from iron(II) oxide (FeO) and silicon dioxide (SiO2). This reaction does not occur in the extraction of copper from chalcopyrite and is not relevant to the Bessemer converter.
Option C: 2FeS + 3O2 → 2FeO + 2SO2
This reaction represents the oxidation of iron sulfide (FeS) to form iron(II) oxide (FeO) and sulfur dioxide (SO2). This reaction occurs during the roasting step in the Bessemer converter.
Option D: Cu2S + 2Cu2O → 6Cu + SO2
This reaction represents the reduction of copper(I) sulfide (Cu2S) and copper(II) oxide (Cu2O) to form copper metal (Cu) and sulfur dioxide (SO2). This reaction occurs during the reduction step in the Bessemer converter.
Based on the analysis above, we can conclude that option A does not occur in the Bessemer converter during the extraction of copper from chalcopyrite.
