Apr 15, 2020 · Moreover, research on RE flotation has rarely considered the use of dissolved sulfate minerals (barite supernatant) as a flotation medium. For example, Ca 2+ is commonly present in flotation pulp and inhibits the flotation of bastnaesite and monazite when using benzohydroxamate as the collector [19] .

Column cells (Figure 1) are flotation devices that also act as three phase settlers where particles move downwards in a hindered settling environment countercurrent to a swarm of rising air bubbles that are generated by spargers located at the bottom of the cell.
Column Flotation • Theory and Practice
Column flotation which employs a counter-current flow of slurry and air bubbles has proved to be a better alternative to the conventional mechanical cells for separation of minerals. Because of the distinct advantages of column flotation over mechanical cells, it is gaining wider acceptance in industry.

replaced by one column each. For the second phase, the barite flotation circuit and regrind flotation circuits were replaced by one column each and the coarse flotation circuit was replaced by two parallel columns. The total installation project was completed during routine maintenance shutdowns and did not result in any lost production.
