Abstract. – Effects of oxide nanomaterials used in flotation process in wastewater treatment. Important challenges in the global water situation, mainly resulting from worldwide population growth and climate change, require novel innovative water technologies in order to ensure a supply of drinking water and reduce global water pollution. For this purpose, highly advanced nanotechnology offers new opportunities in technological developments for advanced water and wastewater technology processes. This paper presents an important method used in the wastewater treatment and in the mineral separation, named the flotation. Also, this paper presents the factors that influence the froth flotation process, such as: nanoparticle hydrophobicity, nanoparticle diameter, particle softness etc.
Key-words: nanomaterials, flotation process, froth flotation, hydrophobicity, nanoparticle diameter, bubble size
