Coarse particle flotation for early gangue rejection application has attracted considerable attention in the mineral industry. Since grinding units consume a significant amount of energy and sometimes stand as the most energy-consuming unit in the process (Curry et al., 2014, Jeswiet and Szekeres, 2016, Hassanzadeh, 2018), the early …
Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.
The Jameson Cell is a high efficiency flotation separator, which uses induced air from atmosphere. Air is induced into the downcomer through the influence of the jet action produced by the pressurized pulp. Compared with conventional flotation machines, the Jameson Cell features high-efficient cleaning, excellent separation …

Flotation equipment is a kind of beneficiation equipment which takes bubbles as the carrier and uses the difference in mineral surface wettability to separate minerals. In the late nineteenth century, flotation as a beneficiation method was explicitly proposed, and various types of flotation equipment were developed, including flotation …
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 …

Research has shown that the impeller tip speed generally varies over a range of 5–7 m/s in mechanical flotation cells and can be as high as 9 m/s, being largely dependent on cell type and size (Arbiter, 2000, Deglon et al., 2000, Fallenius, 1987). In a mechanical flotation cell, the impeller acts as the "engine" that imparts energy to the ...
Prominer can provide SF series self-priming flotation machine and XCF/KYF series pneumatic flotation cell which are mainstream products for the recovery and upgrading of sulfide ores.

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.
