Introduction The precipitation of Al(OH)3 from sodium aluminate solution is a key step of Bayer process to the quality of the products and efficiency of the alumina production. However... in this work are reasonable referring to Ref. [24], in which the values of interfacial tensions vary in the range of 0-100 mJ/m2 for other molecules. As the precipitation process of Bayer liquors......
