    How to Remove Arsenic, Antimony & Bismuth from Copper

    Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.Fungal volatilization of arsenic and antimony and the,,Fungal volatilization of antimony and other group Vb elements has been proposed to have a causal role in the sudden infant death syndrome (SIDS; cot death).
