Abstract
The general objective of this study is to identify parameters that might control the flocculation behavior of phosphatic clays. Studied parameters include addition of acid or base, water chemistry, ph, and initial polymer and solid concentrations. To achieve the goals of this study, the following tests are conducted: (1) mineralogical analysis, (2) chemical analysis of water and solids, and (3) flocculation tests followed by determination of settling rate, filtration rate, and cake resistance. Obtained results indicate that polyacrylamide requirements for flocculation of phosphatic clays depend, generally, on the initial polymer and solid concentration and water chemistry. In addition, correlation of different parameters has resulted in the proposal of several mechanisms to be involved in the studied systems. Most importantly, it becomes evident that further research is needed to identify the exact role of each of the studied parameters.
