Flotation Feed an overview ScienceDirect Topics

The difficulty facing the flotation designer is that the cell performance is a strong function of the size of the particles to be floated, and that flotation feeds contain a wide range of particle sizes. For any given particle size, the effects of impeller speed and bubble diameter can be summarised as follows :. 1.

Fluidized bed desXinhai in fine particle flotation:

The Reflux Flotation Cell challenges conventional flotation cell design and operation in three ways. Firstly, the upper free surface of the flotation cell is enclosed by a fluidized bed distributor in order to fluidize the system in a downwards configuration, counter current to the direction of the rising air bubbles.

Flotation Column: A Process Unit for Cleaning Up Paper

Flotation deinking is a key unit operation in most paper recycling plants for the removal of hydrophobic contaminants from pulp . There is a wide variety of flotation cells available for deinking but the dominant technology typically consists of multiple horizontal flotation cells in series, with each cell being aerated by several injectors.
