ABSTRACT The flotation of desired mineral ores is selectively depressed by the use of an effective amount of a polyoarboxylic acid or salt thereof in a reverse flotation process. As an example, the flotation of iron containing minerals, such as iron oxides or iron powder, is selectively depressedpared to the flotation of silicate gangue thus facilitating the recovery of the desired

THE USE OF COLUMN FLOTATION FOR THE RECOVERY OF

Column flotation devices were re introduced for mineral processing in the late 1960s in Canada by Boutin and Wheeler 1967 at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late 1980s column flotation had became a proven industrial
