Sedimentation and separation of red mud is an extremely complex physical and chemical process.Bayer method dissolving pulp is formed from red mud and sodium aluminate solution in the suspension, because the red mud and red mud particles and solution between the complex physical and chemical effect, make the red mud phase composition, particle size distribution, surface morphology of red mud particles and the solid content of red mud slurry, liquid ingredients, such as red mud slurry temperature precipitation separation process of red mud slurry have obvious influence.If the appropriate flocculant can be selected, the application of flocculant technology can greatly improve the solid-   

liquid separation speed and reduce the size of the separation equipment.The mechanism of action of macromolecular flocculant lies in the effective agglomeration between red mud particles caused by adsorption bridging, surface adsorption and charge neutralization, forming "large particles" and greatly accelerating the sedimentation rate.Different slurry has different sedimentation properties, so it is necessary to select suitable polymer flocculant through experimental study, so as to achieve high efficiency separation of red mud.Product effect: strong flocculation force, fast and stable flocculation process.The flocs formed are small, strong and shearing resistant, which can effectively reduce the content of floating matter in aluminic acid solution and improve the productivity of settling tank.Improve clarification and overflow quality.The base flow liquid-solid ratio is low.Prevent red mud from swelling.Temperature, PH value of small shadow.
