“…The first of these is to consider the full system and to study the influence of the global parameters (liquid and gas flow rates, chemical composition, and nature of particles) on the overall flotation efficiency. [3][4][5][6] The other approach focuses on the simplified system of one or few particles interacting with a single bubble. [7][8][9][10][11][12][13][14] The modeling of the flotation process is based on three elementary microprocesses, namely, the bubble-particle encounter collision, [15][16][17][18][19][20][21] the subsequent attachment, [19,[22][23][24][25] and the detachment.…”

This article deals with the dispersion of solid particles in a liquid agitated by a homogeneous swarm of bubbles. The scale of interest lies between the plant scale (of the order of the tank) and the microscale (less than the bubble diameter). The strategy consists in simulating both the twophase flow of deforming bubbles and the motion of solid particles. The evolution of the spatial distribution of particles together with the encounter and entrainment phenomena is studied as a function of the void fraction and the relative size and mass of particles. The influence of the shape of the bubble and of the model of forces that govern the motion of particles is also considered.

“…By this way the respective influences of different physicochemical and hydraulic parameters (hydrophobicity, nature and size distribution of the particles, air and fluid flow rates, etc.) on the elimination of given solid particles can be scanned, see for example the works of Reay and Ratcliff (1975), Collins and Jameson (1976), Small et al (1997) or more recently Hu et al (2003). Modelling the efficiency at the flotation cell scale can be performed by integrating along the vertical rising of the bubble swarm the number of particles each bubble captures.…”

“…Bokanyi and Csoke 17 stated that efficient flotation performance with the Hungarian Mecsek coal could be obtained only after sufficient liberation between organic and inorganic components was achieved. Small et al found that successful liberation of different components played an important role in achieving selectivity during the flotation of a lead/zinc ore. These findings were also confirmed by Morizot et al, who stated that particle liberation was one of the most critical parameters for a successful flotation process at plant-scale operations.…”

Beneficiation of Himmetoǧlu Oil Shale by Flotation as a Solid Fuel Substitute. Part 2. Process Optimization by a Statistical Approach

The effects of the important flotation parameters on the cleaning process of the Himmetoǧlu oil shale from Turkey were investigated. The individual and multiple interaction effects of conditioning time, flotation time, pulp density, particle size, and frother dosage were determined using statistical analysis and factorial design of experiments. The influence of these parameters on the cleaning performance were evaluated in terms of ash yield, calorific value, and combustible recovery of the concentrates. XRD studies were also carried out to view the variations in the organic and inorganic content of the concentrates. Optimum parameter conditions, which provided the most effective cleaning, were determined by the applied model. It was seen that all parameters affected the flotation performance with varying degrees of significance. At optimum conditions, flotation performance increased and the ash yield of the concentrate decreased to 16.81% with 84.10% combustible recovery, and the calorific value increased to 5564.02 kcal/kg. XRD spectra revealed that the extent of mineral matter removal depended on the flotation performance, and the inorganic matter was effectively removed at optimum conditions.
