Nov 15, 20150183;32;Mechanical flotation cells are not suitable to float particles coarser than a certain size, as the turbulence in the cell is sufficient to destruct the bubbleparticle aggregates. Graeme described how a fluidized bed is an alternative medium to keep the coarse particles in suspension, due to the relatively quiescent environment it provides.

The use of DAF (dissolved air flotation) as an alternative

Dissolved air flotation (DAF) is based on the separation of the solidliquid phases with the aid of small air bubbles (10100 181;m), with high values of interfacial contact area, improving the process efficiency. In the process, the air bubbles and particles or flocs form aggregates, which rise to the surface of the flotation cell to be collected.

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (Oamp;G) from a wastewater stream. Contaminants are removed through the use of a dissolved airinwater solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.

Flotation Column Cells can only carry or recovery so much froth/concentrate for any given diameter. Unlike a mechanical cell on which you can just turnon more air to recover more metal, column cells with not respond that way. A column cell can only carry so much froth to the concentrate launder. Their concentrate production is MaxedOut by design.

The tailings from the flotation cells will be passed from the last flotation cell to the Launderer tray where a surfactant (Shaklees Basic H or an equivalent) will be added. The Basic H breaks down any remaining flotation reagents, allowing the heavy metal particles to sink and prepare the ore slurry for the Diester gravity recovery shaker

The importance of the grinding environment on the flotation behaviour of sulphide minerals and ores has been known for many years (Rey and Formanek, 1960). However, it is not commonly appreciated that the grinding environment may play a key role in controlling fine value mineral floatability, as well as selectivity against sulphide gangue

The ability of a mineral to float depends upon its surface properties. Chemical modification of these properties enables the mineral particles to attach to an air bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell.
