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) 2 FeS (s
Copper matte is put in a silicalined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO 3). Also, some silica is added to the silicalined 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.
What is the role of silica in the extraction of copper? Solution Show Solution. Ores of copper contain iron oxide as impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag.
In the extraction of copper, silica (SiO) acts as a ''''flux''''. It reacts with FeO and removes it as the slag (FeSiO). FeO + SiO gt; FeSiO (Flux) (Slag) Good luck !!

What is the role of silica in extraction of Cu from copper pyrite ore? Answer: Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent). It reacts with solid impurities, such as iron oxide, and forms a liquid slag with density, smaller than the copper matte.
Answer: Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent).... The iron sulfide is also converted into molten slag (reaction is shown above). 14 votes

#0183;#32;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).

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.
