Title: Method for adding red mud precipitation auxiliary in precipitation separation of red mud
Inventor: AMANO HARUO
IPC: C01F7/0653
Filed: 1992-10-15
Abstract: PURPOSE:To reduce the usage of a precipitation auxiliary by preliminarily diluting a red mud precipitation auxiliary agent with a circulated and clarified solution and/or washing water in a precipitating separation process and subsequently feeding the diluted solution to a non-treated red mud slurry. CONSTITUTION:An original slurry P (a red mud slurry to be treated) comprising a red mud and a NaAlO2 solution, i.e. an alumina extract solution from the Beyer process, is fed into a solution thickener T0 in a prescribed amount at a prescribed flow rate. Apart of a clarified solution subjected to a precipitating separation treatment in the solution thickener T0 is circulated as a circulated and clarified solution R1, and the remained clarified solution R2 is fed as a NaAlO2 solution into a precipitation process. The circulated and clarified solution R1 is subjected to the feeding of washing water W and a red mud precipitation auxiliary S such as a water-soluble polymeric coagulating agent and subsequently mixed in a line mixer M. The mixture is added to the original slurry as a precipitation-accelerating agent having a dilution concentration of <=100ppm and then fed into the solution thickener T0. The precipitation- separated slurry is taken out from the bottom of the thickener as a discharging slurry having a high slurry concentration.
