Crude Tin Refining-Tin- - Metalcess

The refining of crude tin is to remove these impurities and recover valuable metals like indium, bismuth and copper, which helps to reduce production cost to a large extent. The common purities in crude tin incude iron, arsenic, antimony, copper, lead, bismuth and sulfur. Crude tin is treated by either fire-refining or electro-refining.
