摘要: A method is disclosed for recovering condensed solidified volatile metals from the slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed to the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials can be removed and recovered. Finely divided slag particles can be separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor results which contains dissolved volatile metal salts of the acid. The acid liquor containing the dissolved volatile metal acid salts is then electrolyzed to reduce the dissolved volatile metal acid salts to the corresponding elemental metal for recovery.
