The patented Concorde Cell technology is the first fine and ultra-fine flotation solution for more finely disseminated and complex orebodies that have previously been inaccessible.
In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch, jigged to yield a finished concentrate and a ...
His design adapts the eponymous Jameson Cell he patented in the late 1980s. In contrast to the HydroFloat, his cell treats fine and coarse together. The flotation feed cycles past an airjet first, where it encounters the high energy useful for attaching fine particles to bubbles. "That's like the Jameson Cell, actually," he said.
Advanced Techniques on Fine and Coarse Particle Flotation Oktay ¸Sahbaz, Ali Uçar, Ça˘grı Emer, and Cengiz Karagüzel Abstract Flotation is a physicochemical process that is used for the separation of hydrophobic particles from hydrophilic ones.
Some of the research claim that Jameson flotation cell can produce a large number of bubbles of size <600 μm in diameter, so this device can be potentially used for the fine particle separation [58].

The passage of the coarse fractions through each impeller eliminates short circuiting and thus, both fine and coarse mineral are subject to positive flotation. ... The capacity of a flotation cell, treating any ore, depends upon facts and conditions which can best be determined by experience and test work.
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.
The process of froth flotation entails crushing and grinding the ore to a fine size. The fine grinding separates the individual mineral particles from the waste rock and other mineral particles. ... Recent column flotation cell projects. In 2018, Industrial Resources Inc. fabricated eight, 18'-0" diameter column cells by 26'-6" tall ...
This paper investigates the reverse flotation of iron ore in a laboratory mechanical, oscillating grid (OGC) and pneumatic flotation cell. The main objectives are to investigate the recovery of coarse quartz (+150 µm) by flotation and fine hematite (−25 µm) by entrainment.
The minimum grade of ore that can be smelted directly without previous ore-dressing treatment varies, depending largely on the natural fluxing characteristics of the ore, total tonnage of ore, distance to the smelter, haulage and freighting costs, and variations in treatment charges as between different ores and concentrates.

Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).
