Abstract
During the roasting of copper ores when both arsenic and antimony sulfides are present, the evolution of arsenic is retarded and the volatilization of antimony increased primarily because of the formation of heteronuclear compounds. These heteronuclear compounds exhibit vapor pressure different from those of their individual parent compounds. Because the arsenic and antimony content in copper ores and concentrates is generally 1 percent or less, the anomalous vaporization behavior of mixed arsenic and antimony oxides and sulfides may be of small magnitude. However, because the phenomenon of preferential antimony volatilization was noted in roasting studies of concentrates and because high-arsenic flue dusts and antimony speiss are sometimes roasted together, the formation of heteronuclear compounds of arsenic and antimony is a factor that should be considered.
