Turbulence and its distribution are of great importance in flotation cell design as they affect suspension of particles, air dispersion and particle-bubble collision rates, which in turn determine flotation performance. However, there is no mature technique to measure turbulence in three phase (liquid-solid-gas) systems such as in flotation cells.

2003-11-1 A new method for measuring froth recovery in industrial flotation cells is proposed. The technique allows measurement of the froth performance in a flotation cell directly, with minimum effect on cell operation. It is based on a combination of two published methods to measure froth recovery; viz., Savassi et al. (1997) and Vera et al. (2000 ...
Read MoreIn the turbulent zone, air is drawn into the flotation cell and turned into swarms of small bubbles dispersed in all directions within the whole turbulent zone by an impeller. These bubbles adsorb frothers and collide with valuable mineral particles rapidly. Then they ascend upwards to the quiescent zone, and ultimately become metastable.

2016-11-10 The 170 cm diameter RCS flotation cell incorporated a variable sidewall height, allowing comparison of a standard aspect ratio cell (145 cm height), with a lower aspect ratio cell (110 cm height, 2.5 m 3 volume). By reducing the cell height, the ratio between high and low shear zones in the cell was increased. The cell geometries are illustrated in Fig. 2.

The flotation plant had two parallel flotation circuits of Metso RCL10 and RCL30 cells. Each circuit consisted of four flotation cells with a capacity of 10 m 3, which were placed in series, and each circuit had four froth outputs. All the tests were conducted in the first cell.

2016-11-4 Runge is working on a number of research projects. Progress made by equipment manufacturers notwithstanding, she thinks there is much more to understand about how turbulence affects flotation in the bigger cells. “A lot of people have just changed one variable and seen correlations and made conclusions from that,” she said.

In conventional flotation cells, the pulp phase is usually divided into two regions, that is, a turbulent zone and quiescent zone. In the turbulent zone, air is drawn into the flotation cell and turned into swarms of small bubbles dispersed in all directions within the whole turbulent zone by an impeller.
