Pico–nano bubble column flotation using static mixer-venturi tube for Pittsburgh No. 8 coal seam

open access: yesInternational Journal of Mining Science and Technology, 2015
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

open access: yesJournal of Materials Research and Technology, 2019
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

open access: yes, 2009
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

open access: yes, 1993
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

open access: yes, 2014
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.

The influence of frother types and concentrations on fine particles' entrainment using column flotation

open access: yes, 2017
Entrainment which is the characteristic feature of fine particles is closely related to water recovery. It is based on the changes depending on the establishment of linear relationship between water recovery and solid recovery.
