Flotation Column This study was performed on a laboratory-scale flotation column built at FPInnovations, Paprican [20]. The column, shown in Figure 1, has a 10.2-cm diameter and a height of 4.65 m. The principle of the flotation column is simple.
Read MoreOct 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.
