Column Flotation Cells - Mineral Processing & Metallurgy

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

What Are Column Flotation Cells? - indres

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

Flotation | Eriez Flotation Division

Column flotation devices were re-introduced for mineral processing in the late-1960's in Canada by Boutin and Wheeler (1967) at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product.

Introduction to Mineral Processing - cpchem

The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.

Non-metallic Mineral Flotation by Microcel Column. The coefficient (n) varies with the Reynolds number of the bubble, but is approximately 2 for most flotation size bubbles. Thus, when particle size is reduced, Pc decreases approximately as the square of particle size, providing an explanation for the difficulty in fine particle flotation in general.

Froth flotation - Wikipedia

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not .
