The red mud settling section is an important link in the alumina production process, which needs to quickly separate the solid from the liquid after dissolution, and there are a large number of positively charged red mud particles in the slurry, which will be stably dispersed in the pulp. It is necessary to add the alumina red mud flocculant to neutralize the electric properties of the red mud particles to achieve charge stability. The fine particles can be flocculated into large groups by using the adsorption bridging action of flocculant, so as to promote the rapid separation of red mud and sodium aluminate solution, and improve the flocculation settling rate.
Therefore, the red mud settler is related to the sedimentation speed, the compression performance of red mud and the quality of sodium aluminate solution, which affects the product quality and production efficiency of alumina. Alumina red mud flocculant is an organic polymer, which has the function of adsorption bridge and electric neutralization, can accelerate the agglomeration of red mud particles, promote the rapid separation of red mud and sodium aluminate solution, improve the flocculation settling speed, and ensure the production needs.
