FrothSense+ - Metso

The trend towards larger flotation cell volumes, which is in part being driven by the increasing pressure on concentrators to reduce CAPEX and OPEX costs, has resulted in an increasing need to be able to control the cell-specific mass pull – the velocity at which concentrate is removed from the cell. A smaller froth surface area to cell ...

Minerals Free Full-Text A Review on Froth Washing in Flotation

2022.8.12  Column flotation cells utilise froth washing. Froth washing involves introducing clean wash water within the froth or externally on top of the froth. The added clean wash water creates a net downward flow of water in the froth, which flushes out gangue particles and reduces the fraction of gangue minerals [27,28,29,30,32,33]. Thus,
