Flotation Process - an overview ScienceDirect Topics

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

Principles of Froth Flotation SpringerLink

The adhesive force with which a particle clings to the air-water interface is opposed by the gravitational drag due to its mass. For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the ...
