A froth crowder device (10) is disclosed for incorporation into a froth flotation cell (12) to improve the froth removal dynamics of the flotation cell. The froth crowder device (10) is positioned within a froth flotation cell (12) above and below the overflow launder, and provides a sloped surface to direct froth toward the overflow launder (28) in an expedited manner. Experimental data confirms that use of a froth crowder device (10) as disclosed expedites movement of the froth toward the launder (28) for more efficient operation, permits operating the rotor (46) of the flotation cell (12) at reduced speeds without compromising the efficiency of operation, and reduces the amount of air necessary to produce a froth in the cell. Experimental data also confirms that little or no surface eddies are observed in froth flotation cells (12) in which a crowder device (10) as disclosed is used. By comparison, flotation cells without use of a crowder device experience increased occurrences of surface eddies which traps the froth within the tank and extends froth residency time to the ultimate detriment of separation efficiency.

L'invention porte sur un évacuateur d'écume (10) se plaçant dans une cellule de flottation (12) pour en améliorer la dynamique d'élimination de l'écume et qui s'y installe au-dessus et au-dessous du trop-plein et constitue un plan incliné dirigeant l'écume vers le trop-plein (28) d'une manière rapide. Les données expérimentales confirment qu'un tel évacuateur (10) facilite le mouvement de la mousse vers le trop-plein (28), améliore l'efficacité de fonctionnement et permet de faire tourner moins vite le rotor (46) de la cellule de flottation (12) sans compromettre le rendement tout en réduisant la quantité d'air nécessaire pour produire l'écume dans la cellule. Les données expérimentales confirment également qu'on observe peu ou pas de remous dans les cellules de flottation (12) comportant un tel évacuateur d'écume (10). Comparativement, on constate dans les cellules de flottation n'en comportant pas un accroissement des tourbillons de surface qui retiennent l'écume dans la cuve et en prolongent le temps de séjour dans la cuve au détriment du rendement de séparation final.
