Role of Turbulence in Mineral Processing Unit Operations

In many unit operations, there are more or less developed turbulent flow conditions. Then, macroturbulence influences the transport phenomena of the particles and microturbulence controls the stresses acting on fluid and solid particles or agglomerates as well as the collisions between particles. Consequently, these conditions have to betaken into consideration for modeling and optimization. The results of corresponding approaches are demonstrated taking classification and flotation as examples. But, at present, extensive simplifying assumptions have to be made.
