Verfahren zur Eliminierung von Abfallprozess schwefligen Säuren und zur Erzeugung stabilen Produkten

摘要

Treatment of sulphur-containing acid residues from industrial processes, to obtain stable products, involves neutralising the acid residues with clay-containing limestone fines and adding the resulting gypsum to a prepared belite cement raw material for regulating the SO3 content so as to give a clinker having a variable setting time (dependent on the SO3 content) and other physical chemical properties.
