Color video or digital cameras have been installed over flotation cells to monitor color, bubble size,
froth movement and other characteristics. These systems are designed so that the camera provides
flotation performance information just as any other sensor might. Factorial tests have been run to
monitor and measure the variation in froth characteristics as a function of flotation control settings.
Ultimately, it is envisioned that froth image sensors can be used to monitor and control the flotation
performance as effectively and for less cost than current analytical systems.
