説明
Dross discharged from practical operations was immersed in a molten lead bath between 703K and 823K to study zinc separarion >from dross on a laboratory scale. Dross was composed mostly of zinc and intermetallic compounds of zinc and iron. Solidified dross and a lead bath were analyzed by X-ray diffraction (XRD) and fluorescent X-ray analysis. The zinc in dross decreased gradually with treatment time, while that of lead increased. Zinc is supposedly separated from both the zinc and intermatallic phases when dross was treated in a lead bath. Zinc floated in lead due to its lighter specific gravity. The amount of zinc floating increased with treatment. Dross treated long time consisted of discrete iron and lead was magnetic. During immersion, lead penetrated dross and replaced zinc. Zinc and lead do not dissolve mutually from the view point of thermodynamics. Iron in dross neither formed compounds with lead nor dissolved in the lead phase. This process thus enabled zinc and iron to be separated from dross in a practical process.
