  • METALLURGY OF COPPER EXTRACTION OF COPPER BLISTER

    Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper 2Cu2S 3O2 è 2Cu2O 2SO2 2Cu2O Cu2S è 6Cu SO2 The copper so obtained is called Blister copper because as it solidifies SO2 hidden in it escapes out producing blister on its surface.
