extraction method of cassiterite

  • Extraction of metal from the ore cassiterite involves

    removal of iron impurity. Solution: The important ore of tin is cassiterite ( S n O 2). Tin is extracted from cassiterite ore by carbon reduction method in a blast furnace. S n O 2 + 2 C → S n + 2 C O. The product often contain traces of iron which is removed by blowing air through the melt to oxidise to FeO which then floats to the surface.
