Flotation Process - an overview | ScienceDirect Topics

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 are placed are at the base of the separation.

Floatation - SlideShare

INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles. Floatation is an extractive process where various minerals can be selectively extracted. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of ...
