  • What is the role of silica in the extraction of copper

    Ores of copper contain iron oxide as an impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag. In the smelting process such chemical reactions are taking place: 1) Oxidizing of the copper pyrite: 2 CuFeS2 (s) + 3 O2 (g) → 2 FeO (s) + 2 CuS (l) + 2 SO2 (g) 2) Conversion of iron oxides and sulfides into molten slag: FeO (s) + SiO2 (s) → FeSiO3 (l)

  • State the role of silica in the metallurgy of copper

    2020-3-1 · During roasting, copper pyrites are converted into mixture of FeO and Cu 2 O. To remove FeO (basic) an acidic flux silica is added during smelting. FeO then combines with SiO 2 to form ferrous silicate (FeSiO 3) slag which floats over molten matter.. Thus, the role of silica in the metallurgy of copper is to remove iron oxide as slag.

  • Why copper matte is put in silica lined SaralStudy

    Copper matte is put in a silica-lined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO 3). Also, some silica is added to the silica-lined converter. Then, a hot air blast is blown. As a result, the remaining FeS and FeO are converted to iron silicate (FeSiO 3) and Cu 2 S is converted into metallic copper.
