| Abstract: | A new process in which a foam alkali can be produced by taking aluminum sulfate residue and waste alkali liquid of zirconium oxychloride as its raw materials, and then sodium metasilicate pentahydrate being made by one-shot slag forming is introduced. The small-scale test shows that the quality index of the product can meet the requirements for HG/2568 - 94. The new process has a low cost, which can avoid the discharge of the waste alkali liquid and the pollution of the residue on an environment, and use natural resource in a better way. Thus, it has good economic & social benefits. |
