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 . In use the first outlet  29  receives a quantity of the selected particles which were not conveyed out of the vessel by the froth layer  13 , and the second outlet  20  receives a quantity of the selected particles in a first by-product of the system. The first by-product comprises a relatively higher percentage of solids compared to the flow of particles and fluid in the first outlet  29 . The flow of the mixture of particles and fluid from the vessel  10  via the first outlet  29  passes to a classification device  31, 76  which separates the flow into two or more fractions on the basis of their size or density or a combination of the two.

Claim (Index 142):
A method as claimed in  claim 140 , further comprising the step of introducing a gas for froth flotation separation into the flow which is directed to the vessel.
