Froth Flotation of Iron Ores

4.2. Column Flotation The application of column cells in the mineral processing industry has gone from virtually zero in 1983 to wide acceptance in 1990[ 57]. The major operating difference between column flotation cells and mechanical flotation cells is the lack of agitation in column flotation which reduces energy and maintenance costs[58].
