The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a cocurrent descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.
Flotation is used for separating particles containing valuable material in the ore and this is achieved when the particles preferentially attach to air bubbles and float to the surface forming a
Design Problems for Larger Cells. Circuit Design and Operation. After almost 60 years of application in this country froth flotation is still by far the most important process for concentrating metallic ores as well as a number of nonmetallic ores including fluorspar phosphate rock and potash. Its use on iron ores and coal is increasing.
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.

The existing literature on optimal design of flotation circuits has been divided into two broad categories. In the first category a generalized integral approach is used wherein the optimal circuit design involves determination of both optimal interconnection of various flotation cells/ banks of cells in terms of structural parameters and
it was soon observed that round tanks held a number of further advantages over the traditional rectangular cells such as better hydrodynamics lower costs and reduced footprint per unit the last twenty years flotation cell sizes have increased almost exponentially and designs of 250 to 300m3 are a well established standard with plans .

The flotation feed is introduced into the fluidized bed and air bubbles are dispersed in the fluidizing water. Coarse particles attach to the bubbles rising through the bed and are lifted into the froth layer that is maintained on top of the cell in the usual way. Particles of galena up to 1 mm in diameter have been recovered in such a bed

Mechanical Design Engineers on the Cell Engineering Team have the opportunity and responsibility to drive impact on the entire product line and product roadmap. Our product requirements demand groundup cell architectures with stateoftheart performance manufactured at volumes that are orders of magnitude higher than the products they power.
Flotation cell technology and circuit design—an Anglo Platinum perspective Pre 1980s—Mineral extraction circuits were characterized by multiple small flotation machines (typically 1m3) with short residence times employing a single millfloat configuration. Typically a threestage crushing closed circuit ball mill comminution circuit
In this study a technoeconomic optimization algorithm was formulated to select the optimal size and number of flotation cells for a fixed circuit structure while considering potential uncertainty in several input parameter including feed grade kinetic coefficients and metal price.
