FROTHING AT THE LIP - STABILITY IN YOUR FLOTATION CELL

Designing a flotation cell with a low froth surface area, (high degree of froth crowding), could lead to a situation where too much material must be transported on the available froth surface area, i.e. a high FCR. In such instances, the froth may collapse due to the relatively high mass of the product rising to the top of the froth, exceeding the amount of weight that the froth structure can ...

This is definitely a rule that has been superseded by the changing design of flotation cells.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 "froth-handling strategy" in mind. In many cases, the use of fewer, larger cells has been of benefit as it has allowed the designer to have less froth surface area ...

The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified. Each of these plays a role in determining how individual solid ...
