Explain the process of obtaining "blister copper" from "copper matte" – InterviewSolution

1.	Explain the process of obtaining "blister copper" from "copper matte" with equations.
Answer» Solution :Copper matte is charged into SILICA lined convertor. some silica is also added and hot air blast is blown toconvert 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.
