  • Patent number: 11596953
    Abstract: A separation system is disclosed for separating selected particles from a mixture of particles in a fluid. The system includes a froth flotation vessel into which in use the mixture of particles and fluid are subjected to an upward flow of an introduced gas to form a froth layer which rises above an interface formed between the froth layer and the mixture of particles and fluid, such that a quantity of the selected particles is conveyed out of the vessel by the froth layer to become a first product of the system. The vessel also has a first outlet arranged in use for receiving a flow of some of the mixture of particles and fluid from the vessel, an entry to the first outlet being located in a region proximate to, but below, the interface. The vessel also has a second outlet arranged in use for receiving a flow of some of the mixture of particles and fluid from a region of the vessel which is located below the first outlet.

  • Patent number: 10850286
    Abstract: A separation system is disclosed for separating selected particles from a mixture of particles in a fluid. The system includes a froth flotation vessel 10 into which in use the mixture of particles and fluid are subjected to an upward flow of an introduced gas to form a froth layer 13 which rises above an interface 14 formed between the froth layer 13 and the mixture of particles and fluid 12, such that a quantity of the selected particles is conveyed out of the vessel 10 by the froth layer 13 to become a first product of the system. The vessel 10 also has a first outlet 29 arranged in use for receiving a flow of some of the mixture of particles and fluid from the vessel 10, an entry to the first outlet 29 being located in a region proximate to, but below, the interface 14. The vessel also has a second outlet 20 arranged in use for receiving a flow of some of the mixture of particles and fluid from a region of the vessel 10 which is located below the first outlet 29.
