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).
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).

Tell me role of Silica in Metallurgy of Copper "? during the process of extraction of pure copper from copper pyrite,SiO2 acts as acidic flux which combines wi Learn to Create the Famous Tic Tac Toe Game in Our Free Robotics Webinar.
· 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.
· The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).
Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.
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. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of .
(i) forms a volatile complex Nickel tetracarbonyl, leaving behind impurities. The nickel tetracarbonyl complex is heated to a higher temperature, decomposes to give pure metal. (ii) Silica acts as a flux, added before roasting to combine with [impurity] and form [slag] (iii) Very highly reactive metals like sodium, Potassium,calcium etc are generally extracted by electrolytic method.
