The incorporation of only 5 wt % GO resulted in an ∼12-fold and ∼18-fold increase in the tensile strength and tensile modulus of PI, respectively, while the PI/rGO nanocomposites were found to have relatively inferior tensile properties. The superior mechanical properties of the PI/GO nanocomposites were attributed to the good dispersion ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

International Journal of Mining Science and Technology

Franzidis and Manlapig conducted an experimental investigation to determine the effect of gas dispersion properties on the flotation rate constant in plant and pilot scale mechanical flotation cells over a range of operating conditions [22]. They concluded that the flotation rate constant was directly related to bubble surface area flux.

Jameson cell - Wikipedia

The Jameson Cell reportedly has the following advantages: relatively low energy use – the only energy that is required to operate the Cell is to pump the slurry through the slurry lens. This means that it requires significantly less electricity than conventional mechanical or column flotation cells.

A possible process approach to enhance the separation result is two-liquid flotation. In this investigation, conclusions regarding the applicability and the process behavior of this approach are presented for different model particle systems with respect to selected process parameters.

Some gas dispersion characteristics of mechanical ...

1. Introduction. The last 10 years have seen significant advances in the measurement of so-called gas dispersion properties in flotation machines, namely: gas superficial velocity (or simply gas rate) (J g), gas holdup (ε g) and bubble size (diameter, D b).From these can be derived the bubble surface area flux (S b = 6J g /D b, where D b is usually the Sauter mean diameter, D 32).

An Investigation of the Gas Dispersion Properties of ...

Based on obtained results, the mechanisms of gas dispersion throughout the flotation cell and gas cavity formation behind the impeller blades have been presented and discussed. A new in-situ optical bubble sampling method was also developed as part of this investigation. The new system allowed an accurate estimation of local bubble sizes and ...
