use of SiO2 in the extraction of copper from copper matte ...

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. Though, the slag can be easily separated from the desired product. Smelting ...

Role of SiO 2 in the extraction of copper from copper pyrites:. The copper matte containing Cu 2 S and FeS is put in silica lined converter in order to remove impurities as fusible slag. Som silica is also added and hot air blast is blown to convert remaining FeS to FeO, which is removed as slag with silica.

The Extraction of Copper - Chemistry LibreTexts

21/08/2020  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. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages ...

Solution (i) In the extraction of copper from copper matte, $$\displaystyle SiO_2$$ reacts with iron oxide to form slag of ferrous silicate and is removed. $$\displaystyle FeO + SiO_2 \rightarrow FeSiO_3$$ (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.
