TL;DR: In this paper, the particle collision, attachment, and detachment are the most critical steps in the flotation process and individual elementary processes (microprocesses) and their effects on flotation efficiency are discussed and the most recent findings are reviewed.

TL;DR: In this paper, an eight-factor five-level Central Composite Experimental Design was conducted for investigating eight important parameters governing the median size and the volume of nanobubbles, including surfactant concentration, dissolved oxygen (O2) content, dissolved carbon dioxide gas (CO2), pressure drop in cavitation tube nozzle, <50 nm hydrophobic particle concentration, < 50nm hydrophilic particle concentration and slurry temperature, and the time interval after nanobble generation.

TL;DR: In this paper, the effects of nanobubble on coal and phosphate froth flotation were investigated and it has been found that the presence of nanoparticles in flotation pulp could widen the coal and phosphorus flotation particle size range, increase the particle surface hydrophobicity, and thus improve the coal flotation recovery.

TL;DR: In this article, the cavitation-generated nanobubbles were used to increase the recovery rate of coarse phosphate particles by up to 10%∼30% for a given acid insoluble (A.I.) rejection.

TL;DR: In this article, the use of nanobubbles in a bank of mechanical cells flotation and column flotation increased the flotation recovery by 8%∼27% at a given product grade.
