Improve minerals recovery and minimize operating costs with Outotec's thickener froth management upgrade. The upgrade helps with froth control, particularly on concentrate thickeners, which can carry valuable minerals into the thickener overflow. Reducing or eliminating froth can save an operation millions in lost minerals per year, as well as reducing maintenance and reagent costs.
Benefits
Improves minerals recovery
Decreases operating costs through reduced reagent consumption
Results in cost savings as less need to clean process water dams or tanks
Reduces the amount of solids in the returned process water
Features
A range of options are available depending on the level and tenacity of the froth:
Rotating floating boom
Sprays and baffle
Effective for light and fluffy froth
Boom and beach
Sprays and baffle
Floating boom replaced with rigid boom
Beach collection point with tank wall penetration for froth removal
Highly effective on denser more tenacious froth
Deaeration tank
Stops froth from entering thickener
Feed enters tangentially to create vortex to aid deaeration
Thickener feed withdrawn from below the liquid level to prevent air and froth entrainment
