During the process of extraction of pure copper from copper pyrite,SiO2 acts as acidic flux which combines with iron oxide(FeO) to form iron silicate(FeSiO3)..
The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting. 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).

Copper Smelting: Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent. (Click here for extraction process). Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in ...
(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'.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
What is the role of cryolite in the metallurgy of aluminium? Answer. Cryolite (Na 3 AlF 6) has two roles in the metallurgy of aluminium: 1. To decrease the melting point of the mixture from 2323 K to 1140 K. 2. To increase the electrical conductivity of Al 2 O 3. Previous Question.
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).
Solution What is the Role of Silica in the Extraction of Copper? Concept: Occurrence of Metals.
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: ...
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).
What is the role of silica in the extraction of Cu from copper pyrite ore? By sidharth on Sat, 05/11/2013 - 03:56 you may go to this link to
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 reduction potentials of zinc and iron are lower than that of copper. In hydrometallurgy, zinc and iron can be used to displace copper from their solution. Fe (s) + Cu 2+ (aq) → Fe 2+ (aq) + Cu (s) But to displace zinc, more reactive metals i.e., metals having lower reduction potentials than zinc such as Mg, Ca, K, etc. are required.
Dec 22, 2017· 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 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).

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 .
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.
Feb 11, 2018· In the course of typical copper and copper alloy process metallurgy, I am not aware of any role that silica would play. While there are many silicate mineral ores, there are only two copper silicate, neither if which are important in the metallurg...
