Natural Surfactants for Flotation Deinking in Paper Recycling

In paper recycling, deinking operations are used to remove the ink from the recovered paper by washing and flotation processes. In flotation, the ink is separated from the fibers by the injection of air in the presence of a foaming agent McCool, 1993 . Rising bubbles foam carry away the ink particles which are separated from the

Scaleup of Flotation Processes

Therefore, determining the correct arrangement and size of the flotation cells based on batch and pilot test results scalingup is extremely important for the overall results.

Influence of impeller speed and cell volume on coal flotation

Experimental results conclude that the flotation performance changes significantly with a change in the impeller speed and cell volume. The lower values of yield and combustible recovery to the froth product in the 2 L cell are reported at higher impeller speeds, whereas the lower value of these indi ors reported for the 6 L cell at a lower

This would allow operators to significantly reduce the size of their flotation lines for a comparable flotation objective. Some discussion will follow about the scaleup criteria,

Production of High Grade Iron Ore Eriez Flotation

Cell Geometry The geometry of flotation column offers some advantages over convention cells. Column cells have a much smaller surface area per unit volume of capacity than conventional cells which promotes froth cro wding. This results in higher froth densities, and when coupled with a stabilizing water addition, permits froth depths of 1m

This is due to the fact that the specific surface area of the cell ratio of the crosssectional area to the volume is much higher for smaller flotation cells. To accommodate for limited specific surface area, especially in high mass pull coal, iron ore, cleaner appli ions, the design engineer uses external launders.

Model Predictive Control for Froth Flotation Plants

Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.
