Abstract: The flotation kinetic model has guiding significance for describing the flotation process, and the flotation rate constant is the key parameter for model construction. In-depth study of the mathematical relationship between the rate constant and different variables can increase the accuracy and applicability of the model; compare the size of the rate constant under different operating conditions and observe its changes, and you can select better operating conditions to evaluate or optimize the flotation process , The type and amount of reagents, and the performance of flotation equipment provide more powerful tools. This paper introduces the continuous development of the flotation kinetic model along with the in-depth study of the rate constant, discusses the research progress of the flotation rate constant K value, and briefly describes the law and development of the time function and distribution function of the flotation rate constant And the role of K value in practical application. Put forward prospects for the continuous development of flotation kinetics, deeply explore the relationship between flotation rate constants and microscopic variables, establish new models, optimize fitting algorithms, and accurately solve the main parameters in the model, which will help to accurately express the float The selection process.
