(PDF) Control of pulp levels in flotation cells

The control of pulp levels in flotation cells is a complex control task. Many different aspects such as cell structure and valve sizing, and their effects on control, have to be taken into account.

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.

A Brief Review of Pulp and Froth Rheology in Mineral

For non-Newtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. In several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s −1 or 160 s −1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].
