浮选过程的各类数学描述已用于工业浮选回路(full scale flotation circurt)的设计中。在可控制的实验室条件下建立的机理描述能确定理论的停留时间。表达浮选特性与现场操作变量间关系的一些经验模型,是根据一种浮选系统建立的,可用于其他任何设想的浮选系统。如果模型是按工业浮选回路建立的,则应用机理模型进行设计所遇到的问题,诸如各比拟放大因子等,将大为减少。然而在实际的作业中有大量的不可控变量,它们影响了这种模型的实际应用。将经验关系与从实际系统中建立的机理模型相结合,将有效地促进模型对浮选流程设计的指导作用。已建立的半经验模型有可能为浮选流程的设计提供一种更为有效的方法。
Various mathematical descriptions of flotation processes have been used in the design of full scale flotation circurt. The mechanism described under controlled laboratory conditions can determine the theoretical residence time. Some empirical models that express the relationship between flotation characteristics and on-site operational variables are based on a flotation system that can be used in any other conceived flotation system. If the model is based on an industrial flotation circuit, the problems encountered when applying the mechanistic model to design, such as the respective magnification factor, will be greatly reduced. However, there are a large number of uncontrollable variables in the actual operation, which affect the practical application of this model. Combining empirical relationships with mechanistic models built from real systems will effectively facilitate the model’s guiding role in flotation process design. The established semi-empirical model has the potential to provide a more efficient method for the design of flotation processes.
