Figure 1. Flotation cell. The figure shows the basic mechanism of flotation cells used in industry. The pulp containing ink is added into water and a mixture of chemicals, including surfactants that form micelles after reaching a critical micelle concentration (CMC). The surfactant reduces surface tension and increases ink hydrophobicity.

A stock liquid is made to flow into a cell through a stock inlet at one end of the cell. The stock liquid is admixed with air bubbles from an air bubble generating device disposed at a lower portion of the cell and extending between the opposite end plates of the cell, thereby forming the stock liquid into a spiral flow. Ink particles are entrapped by the air bubbles to deink the stock liquid ...
