Description
technical field [0001] The invention relates to the field of flotation beneficiation theory, in particular to a particle-bubble collision and adsorption behavior measuring device and method. Background technique [0002] Flotation is a technical method that uses air bubbles as a carrier to separate useful minerals by using the differences in the surface properties of mineral particles. It is widely used in the field of mineral processing because of its advantages such as high separation efficiency and simple operation and maintenance. [0003] The flotation mathematical model reflects the relationship among the flotation output variables, state variables and controllable variables. Applying the model to the actual flotation process helps to improve the separation efficiency. According to the form and meaning of the model, the mathematical model of flotation is divided into dynamic model, flotation empirical model, overall balance model, and flotation microscopic model.
