The main technical innovations in the Bayer process red mud separation and washing new process research and application are: large-scale flat bottom settling tanks and deep cone settlement tanks combined to form the technological process, give full play to the advantages of the two types of troughs, eliminating the need for red mud filtration process , Simplified the process, formed a new Bayer process red mud separation and washing process; improved the E-DUK feeding system of the deep-cone settlement tank introduced, achieved a smooth transition of different liquid volumes; invented the red mud separation washing process The patented technology to eliminate and control foam.
The new process used to separate the overflow flotation material is low, the liquid-solid ratio of the last red mud underflow is low, the production and operation cost is low, and the process flow is simple. Project achievements Technological process belongs to the international initiative. The technical and economic indicators are good, and it has a broad prospect of promotion.
