    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. Silver is extracted from lead ores in large furnaces, a process called cupellation. Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century. In this process, crushed ore …
