Title:
酸洗浄によりスラグから揮発性金属を除去する方法
Document Type and Number:
Japanese Patent JP4001399
Kind Code:
B2
Abstract:
A method is disclosed for recovering condensed solidified volatile metals from slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed onto the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials are removed and recovered. Finely divided slag particles are separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor is obtained from which the dissolved volatile metals are recovered by electrolysis.
