The American Institute of Mining Engineers presented Callow the James Douglas Gold Medal in 1926 for his contributions to the field of flotation. By that time, flotation technology was changing, especially with the discovery of the use of xanthates and other reagents, which made the Callow cell and his process obsolete. Montana Tech professor Antoine Marc Gaudin defined the early period of

Recover Gold by Gravity Method Flotation. The flotation process is now used very extensively on gold ores, not only for concentrating the values without other processes, but also in conjunction with amalgamation, gravity concentration, or cyanidation leaching, to improve recoveries and to give lower treatment costs. In many instances, it is most profitable to recover the gold in the form of

The conditioned mineral slurry is then processed in flotation cells, which are essentially agitated tanks into which finely dispersed air bubbles are introduced. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral laden froth. The remaining unfloated mineral slurry will be discharged as tailings.

Mechanical cells are used with a coarse feed, with a particle size that is just enough to provide high recovery in flotation. This stage generates an intermediate and unliberated concentrate, typically with a significantly lower mass than the original feed. Then only this rougher concentrate is reground, reducing the investment in grinding. The reground product is further concentrated
A flash flotation cell recovers liberated valuable minerals in the cyclone underflow recirculating load before they return to the mill for further grinding. By this it aims to prevent these minerals being over ground. This is shown in Figure 1. Figure 1. Typical SABC circuit with flash flotation cell click to enlarge.

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the forced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise to the top as froth for concentration and collection.
