As with mechanical cells two distinct zones are evident the collection zone extending from the spargers to the frothpulp interface and the froth zone Interaction between these two zones especially the recycle of collected particles from the froth to the pulp is particularly important in understanding design and operation of a flotation.

A froth flotation cell comprising a tank and an impeller rotatably disposed in the tank for suspending solids and dispersing air in a pulp phase or slurry in the tank thereby generating froth from the pulp phase A plurality of radially oriented launders are placed near the top of the tank and have one end connected to an outer launder adjacent the outer periphery of the tank.

Froth is then carried into the froth launder via mass action These separators are specifically designed to have both a small footprint and gravity driven feed system that allows cells to be easily stacked in series or placed ahead of existing conventional or column flotation cells.

A flotation device providing a plug flow hydrodynamic environment and a deep fioth depth Plug flow conditions were found to provide a higher recovery of particles to the froth zone when compared to perfectly mixed conditions which is characteristic of the Denver conventional cell used in the release analysis procedure.

The high efficiency radial launder is shaped to receive the froth uniformly from the cell surface as well as from the typically heavy loaded area near the centre of a forced air machine On passing over the lip the froth accelerates to the perimeter of the cell This unique design rarely requires launder water.

Jan 12 2010018332As with the internal peripheral launder the froth is pushed to the launder by the froth crowder This design however provides more froth surface area The external peripheral launder does not consume cell volume so the effective cell volume for flotation is also higher This launder is predominantly used on smaller TankCells.

Rule 3 quotFroth lip loading should not exceed 1 5 tonnes per linear metre per hour quotThis is definitely a rule that has been superseded by the changing design of flotation cells The new thinking has expanded to also consider the froth carrying rate and emphasises the importance of selecting flotation cells with a quotfroth handling strategyquot in mind.

Aug 14 2017018332Mechanical Cells In a typical installation a number of flotation cells are connected in series such that each cell output froth into a launder and the underflow from one cell goes to the next one The cell design may be such that the flow of slurry from one cell to another can neither be restricted by weirs or unrestricted.
