1. Introduction. Froth flotation is one of the primary mineral processing approaches for separation and upgrading of valuable minerals from their ores (Fuerstenau et al., 2007, Nagaraj and Farinato, 2016).In froth flotation, a collector (a kind of surfactant) selectively attaches to a target mineral using its minerophilic group (Somasundaran and …
The fundamentals of mineral surface complexation and their meaning in flotation are presented and discussed and used to interpret surface charge, as well as surface reactions with collectors, activators and depressants. Surface speciation and flotation principles are correlated for a sulphide (e.g. galena) and oxide mineral (e.g. quartz) system.
open access. Flotation is a complex process that occurs in solid–liquid-gas multiphase systems, and its main factors include the minerals, separation medium, as well as various flotation reagents. The study of mineral properties and interactions with other components such as reagents and water lays the basic theoretical foundation for flotation.
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
Special Issue Information. Dear Colleagues, Mineral resources play a critical role in various material applications. Flotation is a practical technique to separate valuable minerals from gangue minerals based on differences in physical and chemical properties on mineral surfaces. Flotation reagents, such as collectors, activators, depressants ...
Flotation is a very efficient unit operation employed worldwide to separate valuable minerals from gangue materials (this is called froth flotation) and in the treatment of wastewaters as a solid (liquid) water separation, removing several pollutants. This issue covers the advances in these two areas. Froth flotation is the most efficient and ...
The purpose of this Special Issue is to explore the surface interaction mechanisms operating during mineral flotation, especially at the molecular and micro/nano-scale level. Of course, submissions describing other types of studies involving flotation mechanisms are also welcome. The Guest Editors expect that this Special …
