Explain the process of obtaining "blister copper" from "copper matte" with equations.

Text Solution

Verified by Experts

Copper matte is charged into silica lined convertor. some silica is also added and hot air blast is blown to convert the remain FeS, FeO and `Cu_2//Cu_2O` to the metallic copper.
Following reactions takes place:
`2FeS+3O_2to 2FeO+2SO_2`
`FeO+SiO_2to FeSiO_3`
`2Cu_2+3O_2 to 2Cu_2O+2SO_2` `2Cu_2O+Cu_2S to6Cu+SO_2.`
The solidified copper obtained has blistered apperance due to the evolution of S`O_2 ` and so its called blister copper.
