PRODUCTION OF SALT CONTG* ALKALINEEMETAL CARBONIC ACID BY USING AS RAW MATERIAL SLAG OBTD* BY REFINING OF MOLTEN IRON ALLOY

摘要

PURPOSE:To recover alkaline-metal cpds. A as carbonic acid-contg. salt substantially free of impurities, by introducing CO2 into an aq. slag soln. obtd. by the refining of molten iron alloy by use of A to separate a precipitate, and then treating a part of this aq. soln. by the ion exchange-membrane electrolysis.
