Froth Flotation

A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level, the froth continues to flow and cannot be stopped.

Froth Washing in Mechanical Flotation Machines

Gangue Rejection Mechanisms In the Froth Phase. Gangue rejection in the froth phase of mechanical flotation cells is largely achieved by physical means (Table 1): geometrically, hydraulically, or mechanically. Gangue rejection can be maximized by controlling froth residence time, bubble coalescence, or drainage rate.

Coarse chalcopyrite recovery in a universal froth flotation machine

A new froth flotation machine has been developed, known as the NovaCell, which can recover mineral particles over a wide particle size range, from the lower limit of flotation, to an upper limit which depends on the liberation characteristics of the ore. In a single device, the collection of the fines and the coarse particles takes place in separate …

Froth Crowder

The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.
