Lead Refining
The next stage in refining is the softening process where arsenic, antimony, tin, and other elements are removed by oxidation into a lead oxide-rich slag. In this operation, oxygen or oxygen-enriched air is injected into a pot held at around 600 °C. The resultant softened metal contains around 0.003% arsenic, 0.04% antimony, and <0.001% tin.Web
