Abstract: The mineralogical characterization of lead and barium in roasted highlead copper anode slime were studied by a variety of mineralogical techniques. The results showed that limited solid solution of (Pb, Ba)SO4 forms by PbSO4 coming into BaSO4. Meanwhile, (Pb, Ba) is partially replaced by Ag to form (Pb, Ba, Ag)SO4 and sometimes S is partially replaced by Sb to form (Pb, Ba)S(Sb)O4. The structure formed by base metals is complicated as CuO and (Pb,Ba)SO4 are always wrapped by each other. Tiny AuAg alloy particles are always wrapped by (Pb, Ba)SO4 and sometimes parallel eutectic system is formed by (Pb, Ba)SO4 and relatively larger particle of AuAg alloy.

Key words: copper anode slime, roasting, technological mineralogy, lead and barium, phases
