Surface Chemistry is the branch of chemistry concerned with the processes occurring at interfaces between phases, especially that between liquid and gas.

Flotation is a physicochemical process where hydrophobic particulate matters interact with bubbles in aqueous solutions. It is a complex process involving a large number of factors. Particulate-bubble interactions, controlling the efficiency of flotation, require favorable chemical environment, usually realized by addition of various reagents to the flotation pulp. This Research Topic aims to collect papers on recent advances on interfacial studies relevant to surface chemistry of flotation. These may include but are not limited to:
• developments and design of novel flotation reagents
• experimental and theoretical studies on the stability of liquid films (foam and wetting)
• mechanism exploration of mineral/reagent and bubble interactions using advanced tools and instruments
