Hydrodynamic study of a phosphate flotation cell by

2019-1-1  The evaluation of the phosphate particles addition effect in the flotation cell on the power dissipation (Fig. 19a and b) proves that the solid volume fraction affects notably the consumed power. Indeed, when increasing the phosphate volume fraction, the dissipated power increases as well.

Hydrodynamic study of a phosphate flotation cell by

For this purpose, we assimilated the flotation cell to a stirred tank, then we treated two separate cases of hydrodynamic flow using the computational fluid dynamics (CFD) approach. The first one is the single phase flow and the second is the multiphase flow where we took into consideration phosphate rock (solid particles) suspended in the liquid phase (water).
