Natural Surfactants for Flotation Deinking in Paper
surface characteristics. There has been some recent interest in flotation processes in which the surfactant is sprayed on the top of the flotation cell rather than mixed with the pulp prior to flotation DeLozier et al, 2005. Laboratory and pilot plant experiments have demonstrated improvements in the flotation process.
A Simple Flotation DeInking Experiment for the Recycling
Flotation de-inking technology is used in the paper recycling process to preferentially remove hydrophobic contaminants, such as inks and toners from a slurry of fibers in water. In the process fine air bubbles are introduced into the suspension and the hydrophobic contaminants, preferentially attached to the bubblewater interface, are carried to the top of the flotation vessel and are ...

Flotation deinking studies using model hydrophobic
Sep 01, 2000 The role of fatty acids as agglomeration and flotation agents, which act to separate the ink particles in the froth flotation deinking cell, has been clearly established in recent years. In fact, it has been shown from both laboratory de-inking experiments and fundamental surface force measurements that calcium soap particles are produced from ...
Modelling transport phenomena in a flotation deinking
Aug 01, 2006 A laboratory flotation column using Venturi aerators was assembled and used to run continuous flotation trials in order to investigate the contribution of gas flow, froth and pulp retention time in the cell on the flotation de-inking efficiency. The increase of the gas flow induced a nearly linear increase in the ink flotation rate constant.

Air Bubble Size Measurement in a Laboratory Flotation Cell
Air bubble size distribution in a laboratory flotation cell was investigated by using of image analysis technology in this paper. Results showed that it was feasible to determine the air bubble size according to image analysis software. For a porous media-aerated flotation cell, bubble size was dependent on poles size of porous media.
Valorization of waste streams from deinked pulp mills
The pulp suspension was dispersed for 12 min in a laboratory mixer KENWOOD, Germany. The flotation was conducted in a laboratory flotation cell Delta 25, VOITH, Germany at a consistency of 1.3. The air supply was set to 7.4 Lmin. The flotation reject, representing the DS, was collected in a bucket, and the amount was determined ...
1 Froth Flotation Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5 Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
