The book takes the flocculation behavior of full tailings as the research object. Firstly, the important factor of shear rate was introduced to conduct experimental research on the influencing factors of full e tailings flocculation, and the evolution law of floc size and optimal flocculation conditions under different factors are obtained; Secondly, an equation was established for the flocculation process of full tailings, including the aggregation and breakage of flocs, and a kinetic model for full tailings flocculation (FT-PBM) was constructed; Then, FT-PBM was coupled with CFD to simulate and study the flow field characteristics and flocculation behavior in the feedwell; multi-objective optimization was carried out on the key parameters of the feedwell, using the average diameter of the tailings flocs at the outlet of the feedwell, the effective flow rate of the feedwell, and the uniformity index of the solid volume fraction distribution of the tailings slurry on the circumference of the outlet of the feedwell as evaluation indicators for the flocculation behavior of the tailings; Finally, the kinetic of full tailings flocculation and the simulation method of full tailings flocculation behavior in the feedwell were applied to analyze the operating effect of the DCT feedwell in a mine, and optimization suggestions for process parameters were proposed.
