One-step acid solution method solid-liquid sedimentation separation technology is the core technology of fly ash acid extraction of alumina.This paper adopts single factor test research method for sedimentation separation process,focusing on the effects of flocculant type,solid content of slurry,slurry temperature and flocculant addition amount on the solid-liquid separation and sedimentation effect of diluted slurry,and obtains the optimal process parameters.It provides a theoretical basis for the optimization of the solid-liquid settlement separation technology of fly ash extraction of alumina,and also has a great reference for the application of flocculants.
