202085 · The introduction of synthetic, high molecular weight, water-soluble polymer flocculants was a turning point in tailings dewatering within the minerals industry. Gravity thickening had previously relied on coagulants and natural products (e.g. starch) to aggregate particles and accelerate settling. Synthetic flocculants enable much larger ...

20231019 · The three-dimensional model of the high-efficiency sedimentation tank was con-structed at a scale of 1:1 with the engineering prototype using ANSYS Design Modeler (Figure 1). It consisted of a flocculation zone and a plug-flow/clarification zone. The cen-ter bottom of the flocculation zone is equipped with a 700 mm diameter cylindrical wa-

200881 · The beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with Na 2 CO 3 and PAS at pH about 9–10, but it is sensitive to the content of kaolinite. For the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the Al 2 O 3 recovery of 87.0% and Al 2 O 3 /SiO 2 ratio . Acknowledgement
