It reacts with gangue (FeO) to from FeSi0 3 (slag) which is easily removed. Question 58. How is chemical reduction different from electrolytic reduction? Name a metal each which is obtained by
(ii) Copper matte contains Cu 2 S and FeS. In the blast furnace, copper matte is added with powdered coke and silica. The oxidation of ore takes place in this process. As a result, cuprous oxide and ferrous oxide are produced. The role of silica in this process is to remove the iron oxide obtained as ''slag''.
Role Of Silica In The Extraction Of Cu From Copper Pyrites . During the roasting of pyrite ore a mixture of feo and cu2o is obtained the role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting as slag then feo combines with silica to form iron silicate fesio3 .
Silica acts as an catalyst in the extraction of copper. This is the role of silica in extraction of copper. HOPE THE ANSWER HELPS!!!
The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting as ''slag''. If the sulphide ore of copper contains iron, then silica (SiO 2) is added as flux before roasting. Then, FeO combines with silica to form iron silicate, FeSiO 3 (slag).
The Gibbs free energy of formation (Δ f G) of Cu 2 S is less than that of H 2 S and CS, H 2 and C cannot reduce Cu 2 S to Cu.. On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu.. C (s) +Cu 2 O (s) → 2Cu (s) + CO (g). Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore ...
