How to Remove Arsenic, Antimony & Bismuth from Copper

roasting that, I venture to say, would be more effective without the addition of white metal. In roasting copper, the removal of arsenic and antimony proceeds with notably greater rapidity after the copper has become dry (i.e., when it is saturated with cuprous oxide) than when it still contains appreciable quantities of iron and sulphur.
