The rotating stator draws both air and slurry to disperse bubbles into the cell. In a column cell, the flotation feed enters near the top of Jameson cell - Wikipedia The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for Flotation kinetics of a pyritic gold ore - ScienceDirect Jan 17, 2011  Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant HydroFloat® Flotation Eriez Flotation Division About Eriez Flotation.

Also, ’s Column Flotation cells Artisanal and Small-Scale Gold Mining Without Mercury Slu design can lead to higher gold recovery if the force of the water traveling through the slu is decreased. A series of rifles can help break the flow to improve recovery. A zig zag slu also achieves this by creating a drop between the first and second platform that disrupts the velocity of the water as it travels down the slu.

The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.
