Silvia Serranti, Giuseppe Bonifazi, in Use of Recycled Plastics in Eco-efficient Concrete, 2019. 2.4.4 Flotation. Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015).In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they

Flotation | ore dressing | Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

Flotation Froth an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
