Flotation Cell - an overview ScienceDirect Topics

The MAC flotation cell was developed by Kadant-Lamort Inc. It can save energy compared to conventional flotation systems. 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.

The effect of cell hydrodynamics on flotation performance ...

An analysis of the flotation cell performance showed that the overall copper recoveries were very similar for the conditions tested. However, by decoupling pulp effects from froth effects it was possible to determine whether the changes made affected the pulp zone and/or froth zone responses. The analysis showed that the overall recovery had the potential to be up to 10% higher if not limited by froth recovery. Comparing the metallurgical performance

Productive froth flotation technology FLSmidth

Efficient flotation for all applications and wide particle size range. There are many factors that can affect your flotation process. The two aspects that have the strongest impact on a flotation circuit’s efficiency and performance are metallurgical recovery and flotation cell availability. Fluctuations in feed characteristics can lead to recovery losses. The inability to handle changes in feed size and

Flotation stabilization and optimization - SAIMM

It is possible to obtain good performance from a flotation plant but it has proved difficult to maintain such performance. Recovery rates on a flotation plant can be around 90% and often lower, making flotation one of the least efficient processes in the concentration path. Hence, over the last few decades much research and development has gone into the
