Attachment of particles and droplets to bubbles—the latter being of various fine sizes and created by different techniques (as described in detail)—forms the basis of flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays a significant role in this area, in order for separation to be effective, as stressed. This (brief) review particularly discusses wastewater treatment applications and the effect of bubble size (from nano- to micro-) on the flotation process.

从微泡到纳米泡：对浮选的影响

颗粒和液滴附着在气泡上——后者具有各种细小的尺寸并通过不同的技术（如详细描述）产生——形成了浮选的基础，这一过程确实起源于矿物加工。然而，正如所强调的，为了使分离有效，化学通常在该领域发挥着重要作用。这篇（简短的）评论特别讨论了废水处理应用和气泡大小（从纳米到微米）对浮选过程的影响。
