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.
