Role Of Sio2 In Extraction Of Copper From Copper Matte

What is the role of sio2 in the extraction of copper from ...

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).

State the role of silica in the metallurgy of copper.

7-2-2019· 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).

Describe the role of the following:(i) SiO toppr.com

(i) In the extraction of copper from copper matte, SiO2 reacts with iron oxide to form slag of ferrous silicate and is removed. FeO + SiO2 → FeSiO3 (ii) In froth floatation process, to separate PbS and ZnS from ores, NaCN is used as depressant. It selectively prevents ZnS from coming to the froth and PbS is removed along with the froth.
