In response to the problems of muddy overflow and uneven distribution of materials at the outlet of the feedwell in the DCT, this book focuses on the flocculation behavior of full tailings as the research goal. Firstly, based on the evolution law of floc size in the shear-induced bridging flocculation process, a kinetic model of full tailings flocculation was established to describe the flocculation process of full tailings quantitatively. Then, using computational fluid dynamics (CFD) coupled with the full tailings flocculation kinetic model, the flocculation behavior of the full tailings in the feedwell was numerically simulated and studied, and the process parameters were optimized with multiple parameters and objectives. This book aims to develop further and improve the flocculation and thickening theory of full tailings, promote the development of deep thickening technology, and solve the bottleneck problem of paste-filling technology.
