Abstract

In this paper we focus on physical & chemical aspects of AlF3∙3H2O crystals dehydration process. A new highly efficient single-stage method for drying and calcination of AlF3∙3H2O crystals is presented for the first time. In this method a countercurrent drum dryer-calciner of original design is used. The method ensures high quality product (more than 97 % of AlF3 with high flowability) and low heat loss due to combining both drying and calcination processes in one dryer-calciner. Economic factors of this method are assessed and compared with existent methods.

Keywords: fluorosilicic acid; alumimium fluoride; aluminium fluoride trihydrate; dehydration; drum dryer-calciner
