Removal of Antimony from lead?

28,088. if it's just antimony you can swage it and still retain the softness. you might could use a borate to capture and remove the antimony from the alloy. but to do it at home would take about 30 pounds of borate to clean 15 pounds of lead and quite a bit of time. I don't know how you would remove the arsenic though.
