Silver Mining and Refining | Education

Lead ores containing silver are extracted by cupellation, a process developed by the Chaldeans as early as 2,500 B.C. Today, the cupellation process involves heating crushed ore on a porous bed of bone ash until it melts. The lead and other impurities are absorbed into the bone ash, and the molten silver is drawn off.
