1/10/1992 SIMULATION Fig.3 1.2m diameter simulation Column flotation of iron ore 1193 Air rate Air usage in the laboratory column averaged 24.6 Kg/m3. In comparison the 1.2 m diameter column averaged 21 Kg/m3 but had a wider range which reflected the column usage: the low carrying capacity numbers were found in the low feed cases, and the high capacities in the negative bias tests.
Column flotation is being given serious consideration for this service due to the low capital and operating cost of the equipment and the potential of improving metallurgical performance. This paper describes the basic procedures for examining the feasibility of column flotation for reverse silica flotation in iron ore processing plants.
1/11/2020 The typical feed to a flotation system in the iron ore industry consists of particles in the size range between 10 µm and 300 µm. The slimes fraction (<10 µm) are removed using hydrocyclones prior to flotation and the top size is limited to 5–10% greater than 150 µm.

2/1/2012 Various advantages of the column flotation cells have been reported, but a negative report on the column flotation of iron ore was also found in the literature. With the depletion of high grade iron ore, the removal of alumina containing minerals and phosphorous from low grade iron ore has received increasing attention in iron ore industry.
