Abstract

Soda slag, produced as the solid waste from the ammonia-soda process, was treated by heating, adding additives and other methods. It was found that the chlorine ion content changed with the treatment of heating or adding additives. Heating treatment showed little effect on the decrease of chlorine ion content. The addition of additives, especially coal ash, had an effect on reducing the chlorine ion content in soda slag. Moreover, with the addition of coal ash, the chlorine ion content decreased gradually. The chlorine ion content reached 0.078 g/g (7.8%) at the amount of coal ash 10%.
