这篇论文回顾了最近发展的浮选设备的基本原理。提出了借助空穴气核来捕收颗粒的机理，理论分析空穴／气核加速颗粒－气泡吸附提高浮选速度的实际应用证明了这一机理，同时提供了改进浮选设备设计的方式，着重强调二段吸附模型。一些浮选槽采用了这个模型所取得的快速浮选的效果可解释为二段吸附作用的结果。第一阶段是气核／空穴的产生以及在矿浆和流体空穴里通过搅拌和高溶解气体含量加强气核／空穴与颗粒表面的接触。第二阶段，也就是通过高气体含量和静流条件来加强用传统的浮选粒度气泡捕集气核－活化颗粒。
This paper reviews the fundamentals of the recently developed flotation equipment. The mechanism of collecting particles by hole gas nucleus is proposed. The theoretical analysis of the application of holes / gas nuclei accelerating particle-bubble adsorption to improve the flotation speed proves this mechanism and provides a way to improve the design of the flotation device. Emphasis on two-stage adsorption model. Some flotation cells using this model obtained by the rapid flotation effect can be interpreted as the result of two-stage adsorption. The first stage is the production of gas nuclei / holes and the contact of the gas nuclei / holes with the particle surfaces by stirring and high dissolved gas content in the pulp and fluid cavities. In the second stage, gas-particle-activated particles are enhanced by conventional flotation particle size bubbles with high gas content and static flow conditions.
