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.
Toxic chemicals are used in the flotation process to separate the copper and molybdenum out of the milled powder. this flotation process is the major extraction method at duvalsierrita mine because of the poor quality of the copper at this site. some chemicals produce bubbles that that the copper adheres to and the bad stuff falls to the bottom.
