AMIT 145: Lesson 5 Froth Flotation – Mining Mill Operator ...

Flotation Columns. Initial column was invented in 1907. Commercial development was minimal until the 1980's due to sanding of particles in the bottom of the cell. The ability to use wash water to remove entrainment revived the interest in flotation columns. L/D ratio is also significant for ultrafine particles.

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.

Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

Jameson cell - Wikipedia

In a conventional flotation column, the void fraction is similarly low, and so the probability of particle–bubble contact is increased by increasing the height of the column to provide greater residence time. Traditionally, the ore slurry and the air are introduced separately to the flotation cell (see Figure 2).

Column Flotation. Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation .

Microbubble Flotation Column - Mineral Processing & Metallurgy

Microbubble Flotation Column. Tailings slurry is pumped from the base of the column through the static mixers, where air and slurry are mixed under high-shear conditions to create the bubble dispersion. As the air-slurry mixture passes through the stationary blades located inside the mixer, the air is sheared into very small bubbles by the intense agitation.
