What Is Silver Smelting? (with pictures)

Zinc concentrates that contain silver are also roasted and sulfuric acid is added to leach away the zinc. Slag fuming is then used to mix the remaining ore with coke and air to produce lead bullion in the silver smelting furnace. This lead bullion is then processed in the same way that lead ores are to produce silver, using the same type of smelting equipment.
