Abstract
A flotation arrangement, a flotation plant and a method related thereto are disclosed. The flotation arrangement includes a first flotation section and a second flotation section. The arrangement further includes a dewatering system for separating solid material and liquid to obtain a dewatered solid material stream and a separated liquid stream, and the dewatering system is arranged before the second flotation section and connected thereto for leading said dewatered solid material stream to the second flotation section and the arrangement includes recovery means for recovering the separated liquid stream.
Claims22
A flotation arrangement comprising:
- a first flotation section including a first flotation unit comprising a mechanical agitator, and
- a second flotation section including a second flotation unit, which comprises
- i) a fluid bed device comprising devices for creating a fluid bed, and/or
- ii) a froth device comprising devices for creating a froth layer, wherein particles are fed for interaction with froth layer in the froth layer, under the froth layer close proximity thereof, or above the froth layer, or any combinations thereof,
- wherein the arrangement further comprises a dewatering system for separating solid material and liquid to obtain a dewatered solid material stream and a separated liquid stream, and said dewatering system is arranged before the second flotation unit and connected thereto for leading said dewatered solid material stream to the second flotation unit and the arrangement comprises recovery means for recovering the separated liquid stream.
A flotation method for separating valuable minerals from a slurry, wherein the method comprises the steps of:
- treating the slurry in a first flotation section including a first flotation unit comprising a mechanical agitator,
- subsequently, treating the slurry in a second flotation section including a second flotation unit, which comprises
- i) a fluid bed device comprising devices for creating a fluid bed, and/or
- ii) a froth device comprising devices for creating a froth layer, wherein particles are fed for interaction with froth layer in the froth layer, under the froth layer close proximity thereof, or above the froth layer, or any combinations thereof,
- wherein the method further comprises the step of treating the slurry in a dewatering system for separating solid material and liquid to obtain a de-watered solid material stream and a separated liquid stream, and said dewatering system is arranged before the second flotation unit and said dewatered solid material stream is led to said second flotation unit and the separated liquid stream is recovered.
