Column Flotation Cells

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.

Coarse particle flotation: A review

In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse air flow into fine bubbles.

Coarse particle separation by fluidized-bed flotation: A …

As another FBF device, the NC (invented by Graeme J. Jameson) is a novel flotation machine [30, 31]) in which a circulating stream with a high-shear bubble contactor keeps a bed of coarse particles fluidized, and the froth transports out as a single concentrate (Fig. 3).In a NC, the tail consists of two streams: one from the column's top called the overflow, and …

Flotation

Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13, 14]. So, flotation of fine particles is one of the major challenging tasks.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …
