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).
The essential mechanism of flotation involves the attachment of mineral particles to air bubbles in such manner that the particles are carried to the surface of the ore pulp, where they can be removed. The process encompasses the following steps: 1. Grinding the ore to a size sufficiently fine to liberate the valuable minerals

For the coarse grinding process, classic crushers are utilized. The primary and secondary grinding is performed in semi-autogenous (SAG) or autogenous (AG) mills, and in ball or rod mills. If the raw material is distributed suffienciently fine, the precious mineral will be separated from the burden rock in flotation cells (wet classification).
