  • Flotation columns: Getting the most from fine ores Outotec

    In iron ore processing, for instance, they are commonly used to remove silica. In direct flotation, columns have been used mainly for cleaner stages due to their capacity for generating highgrade froths with fine material. The most common configuration involves a rougher with mechanical cells and a cleaner with columns,

  • Froth flotation Wikipedia

    Froth flotation is one of the processes used to recover recycled paper. In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies. Normally the setup is a twostage system
