Flotation Cell - an overview ScienceDirect Topics

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.

1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
