Abstract
This invention relates to the recovery of silver values from silver chloride or mixed chlorides including silver chloride. A pyrometallurgical process is provided in which chloride residues are smelted with an agent such as sodium silicate that provides alkali metal oxide without generating gases, such as carbon dioxide, that would result in foaming during smelting to a material extent.
