The Silver Extraction Process athens123.com

The silver that remained at the bottom of the cupel was run off and solidified into blocks. Since lead was also valuable, it was recovered by placing the litharge (lead oxide) remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was run off and formed into rods.
