摘要
This article introduces briefly the main organics sources in Bayer process alumina production and the harm due to accumulation during process flows, specifies the organics removal methods applied generally in world alumina refineries, and explains briefly advantages & disadvantages of each method. The article stresses the super-concentrated organics removal method developed successfully by GAMI with Guizhou University together, which not only has good organics removal effects (total removal percent of 57-66%), but also effectively removes the carbonates in the process flow.
