Oct 16, 2017  In direct flotation, columns have been used mainly for cleaner stages due to their capacity for generating high-grade froths with fine material. The most common configuration involves a rougher with mechanical cells and a cleaner with columns, after regrinding the intermediate concentrates. This type of flowsheet aims at minimizing grinding costs.

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 ...
