ABSTRACT The interaction between bubbles and solid particles is an important mechanism in many industrial processes and flotation is a significant component of the most utilized applications. While flotation of mineral ores deals with fine particles and larger bubbles, the aim of this review is to focus on the opposite case; the interaction between smaller bubbles and larger particles encountered mostly in plastic flotation. Plastic flotation seems to be one of the appropriate methods for separating plastics, which is necessitated by increasing plastic consumption and the growing need to recycle. The first part of the article focuses on the problem of the collision of a bubble with a particle, both spherical and planar. The collision efficiency is discussed. The second part is devoted to the problem of liquid film rupture and the creation of the three-phase contact line. The third and final part focuses on the problem of the three-phase line expansion and the effect of surfactants on the resulting bubble stability.

浮选过程中小气泡和大固体颗粒之间的相互作用

摘要气泡和固体颗粒之间的相互作用是许多工业过程中的重要机制，浮选是最常用的应用的重要组成部分。虽然矿物浮选处理细颗粒和较大的气泡，但本综述的目的是关注相反的情况；塑料浮选中主要遇到的较小气泡和较大颗粒之间的相互作用。塑料浮选似乎是分离塑料的合适方法之一，这是由于塑料消耗量的增加和回收需求的增加而必需的。文章的第一部分重点讨论气泡与粒子（包括球形和平面）碰撞的问题。讨论了碰撞效率。第二部分专门讨论液膜破裂问题和三相接触线的产生。第三部分也是最后一部分重点讨论三相线膨胀的问题以及表面活性剂对所得气泡稳定性的影响。
