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 115):
A separation system as claimed in  claim 114 , wherein fresh feed of selected particles in a mixture of particles in a fluid combined with a flow gas which is introduced via an entry port in the lowermost region form part of the fluidised bed of particles suspended in liquid, through which bubbles of gas flow upwardly toward the uppermost region.
