The technological technique for subsiding separated red mud is used in the process of aluminium oxide producing by the sintering method. The composite flocculant of red mud is a composite which consists of sodium polyacrylic acid and alkali carbonate. Sodium polyacrylic acid dissolves in a of carbon solution to make up the solution of this composite flocculant. The floccular temp. of red mud is 60 deg.-95 deg.C. The feature of the separating red mud technique described here includes quick separating speed, high adaptability and low cost. The subsider is substituted for the subsiding filtrator. The structure of the subsider is simpler than that of the subsiding filtrator. |
