Abstract

PURPOSE: To efficiently recover silver by adding lead and/or zinc to a molten bath of lead chloride dross while agitating the bath to separate a metallic layer contg. silver at a relatively high concn. at the bottom of the bath.
CONSTITUTION: Lead chloride dross formed by treating lead fearing noble metals with chlorine is heated to about 500W600°C, and while agitating the molten dross, lead and/or zinc is added to the dross preferebly in the form of granules. As the added lead or zinc is melted, a metallic layer contg. lead, silver, copper, zinc, etc. is formed at the bottom of the dross layer. Thus, silver and copper in the dross are concentrated in the metallic layer, and silver can be recovered very easily.
