A Holistic Approach to Flotation Mass Pull and Grade Control
This approach reduces the flotation plant to several concentrate producing units rather than several flotation cells. The difficulty associated with flotation mass pull control comes from the constantly changing feed characteristics, stringent product quality requirements and the economic need to maximize the recovery of a finite resource.

Froth Washing in Flotation | Encyclopedia MDPI
Froth flotation is a mineral processing technique that is popular when processing low-grade ores. It involves introducing chemically treated, finely ground ore in the form of a slurry into a flotation cell where the air is also added in the form of bubbles. The cell is agitated resulting in the air bubbles rising to the top and creating a froth, as …

Flotation Cell (Frothing) Air Control in Mining Operations
Flotation cells are a common ore recovery technique applied in ore and mineral mining operations such as copper and gold. The fotation cell is used to foat ore particles away from the crushed ore/rock mix, by driving air into the bottom of the cell to form bubbles which foat to the top of the main body of liquid to create "froth."
