Refining and Casting

Crude lead produced during smelting operations is remelted in cast iron kettles and refined by the addition of reagents, such as sulfur and caustic soda. The purified lead is then cast into molds or ingots.

Significant lead emissions can occur from poorly controlled refining, casting, and drossing operations.
