Reclaiming spent acid is a key step in the manufacture process of detergent-used zeolite 4A from Montmorillonite because it relates not only to the manufacture cost of zeolite 4A product but also to the environment problem. This paper presented with three reclaiming methods and stressed on the method in which the aluminium was reclaimed in form of ammonium alum. It involved the principle. the effect of conditions, and the material and economic balance. This method proved to be reasonable ,effective and economical.
