Two inorganic-organic hybrid polymers, Al(OH)3-polyacrylamide (Al-PAM) and Fe(OH)3-polyacrylamide (Fe-PAM) were synthesized and used in flocculating model tailings (5 wt% kaolin suspensions) and laboratory extraction tailings. For comparison, a commercial anionic flocculant, partially hydrolyzed...

The distributed framework has been recognized as a promising framework for handling the large size and the strong interaction of modern integrated chemical processes. Compared to distributed process control, its dual problem - distributed state estimation which is equally important, has received...
