Picobubble Column Flotation of Fine Coal: .

Froth flotation is widely used in the coal industry to clean −28 mesh (0.6 mm) or −100 mesh (0.15 mm) fine coal. A successful recovery of particles by flotation depends on efficient particle-bubble collision and attachment with minimal subsequent particle detachment from bubble. Flotation is effective in a narrow size range, nominally 10–100 µm, beyond which the flotation efficiency ...

Flotation is a complex faceted process that can be separated into three main areas: the coal, the chemistry and the machine, as shown in Figure 1. To solve plant issues it is important to understand how different factors within these areas affect and control flotation performance for a particular system. Factors within the coal and

A full-scale Microcel™ flotation column was trialled at the BHP Coal Peak Downs Mine and Saraji Mine coal preparation plants for the treatment of 0.5 mm × 0 (−500 μm) coal. By using deep froths and counter-current froth washing, the Microcel™ columns have been demonstrated to achieve substantially lower product ash compared to conventional flotation cells when treating slimes fractions.

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...

Column Flotation of Fine Coal

Flotation samples were prepared by grinding finely pulverized (-65 mesh) samples of precleaned Pittsburgh No. 8 seam coal for 4 minutes in a stirred ball mill. This procedure produced a mean particle size of =10 µm. The samples were diluted to a desired solids content and reagents added as specified by the experimental design.
