Separation Of Gold From Lead Ore

Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.

How Gold Is Refined: A Step

How Gold Is Refined: A Step

When the cupel is heated, the lead seeps out through the porous holes in the cupel, leaving behind just the gold in a bead-like shape. This bead of gold is known as the prill. To separate the gold from the silver, the refiner places the gold bead in nitric acid or a combination of hydrochloric and nitric acids. A Lab Assesses the Gold
