Pico–nano bubble column flotation using static mixer-venturi tube for Pittsburgh No. 8 coal seam
The flotation process is a particle-hydrophobic surface-based separation technique. To improve the essential flotation steps of collision and attachment probabilities, and reduce the step of detachment probabilities between air bubbles and hydrophobic ...

Recovery of pyrite from copper tailings by flotation
Tailings that are generated in the copper concentrate production contain great amount of sulfide mineral, in particular pyrite. Pyrite in contact with water and oxygen might oxidize spontaneously and originates a serious environmental problem.

Effects of frother type on single bubble rise velocity
The addition of frother in flotation has two main functions, to help reduce bubble size and help produce a stable froth. A role of frother on bubble behavior in pulp zone is usually not considered.

Frother/collector interactions in thin froth films and flotation
Thin aqueous equilibrium film studies and surface tension measurements on a mixed surfactant system consisting of polyethylene oxide (a model frother) and potassium ethyl xanthate (a model collector) enable the interaction between the two surfactants at ...

Development and applications of frother analysis in flotation circuits
Flotation machines disperse air into bubbles using a variety of devices. Since the characteristics of the bubble population are controlled by frother, measurement of frother concentration it is vital to understand and control performance.

Mechanical flotation of hydrophilic particles in the presence of frother [PDF]
W artykule zaproponowano metodę oceny zdolności spierniaczy flotacyjnych do wyniesienia mechanicznego ziaren podczas przepuszczania powietrza przez zawiesinę ziarn hydrofilnych. Polega ona na pomiarze wyniesienia mechanicznego ziarn w komorze flotacyjnej
