Talk:Froth flotation - Wikipedia

I think "flotation" should remain a separate keyword and not integrated into "froth flotation". In the paper industry, flotation is the key process in the recycling process for recovered paper, the deinking process. Nobody uses the term "froth flotation". I might find the time to suggest updates for both the keywords flotation and deinking.

Dynamic Modeling and Real-Time Monitoring of Froth Flotation

A dynamic fundamental model was developed linking processes from the microscopic scale to the equipment scale for batch froth flotation. State estimation, fault detection, and disturbance identification were implemented using the extended Kalman filter (EKF), which reconciles real-time measurements with dynamic models. The online measurements for the EKF were obtained through image analysis of ...
