Estimated Water Requirements for the Conventional ...

at a conventional flotation circuit facility. When the amount of water reclaimed from the TSF is insufficient to meet the plant’s requirements, the lost water must be replaced from sources of “fresh water,” which include lakes, reservoirs, rivers, and wells; precipitation and runoff collected in the TSF may also be sources of makeup water.

1 Froth Flotation – Fundamental Principles

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
