Describe the role of SiO_(2) in the extraction of copper from copper matte. Write chemical equations for the involved reactions. |
|
Answer» Solution :Copper matte is charged into silica line CONVERTOR and hot air is blown. The following reactions take place : `{:(2FeS+3O_(2) to 2FeO+2SO_(2)),(FeO+SiO_(2) to FeSiO_(3)),(2Cu_(2)S +3O_(2)to 2Cu_(2)O+ 2SO_(2)),(2Cu_(2)O +Cu_(2)S to 6Cu+SO_(2)):}` We obtain BLISTER copper due to the EVOLATION of `SO_2`. |
