NIOSHTIC-2 Publications Search - 10009145 - A novel rapid

The U.S. Bureau of Mines has developed a fast air-injected hydrocyclone-shallow tank fast system. Conventional cell kinetics are a compromise between two conflicting requirements, the need for an agitated for rapid bubble-particle collision, and a for bubble-pulp separation. The Bureau of Mines has designed a system in which bubble-particle colli

Sampling from large flotation cells - LICENTIATE T H E SIS

The results show segregation inside the cells, with the having lower particle size P 80 and lower weight % solid. The grade profile in the vertical direction was relatively constant even though the P 80 and weight % solid decreased in the . The smaller particles in the contained a higher fraction of

The Effects of Frothers and Particles on the

ly, systems may be viewed as consisting of two : pulp and froth. The pulp is characterized by gas hold-up ca. 5% - 25% with regions of turbulence designed to promote bubble particle interaction. The froth is characterized by high gas holdup typ. 85%- - 95% vol and a relatively regime of up

Two-phase simulations of an off-nominally operating

Strangely, at the of the tank, the turbulent model gave closer agreement with the measured horizontal velocities than the laminar model. This peculiarity should be rather attributed to the small size of the employed lab scale tank, which did not allow vortices from the reaction to sufficiently decay before

[PDF] The Effect of Cross Section of Mechanical Flotation

In a mechanical flotation cell, the formation of the the and the is essential for effective flotation. The turbulent zone affects solids suspension, gas dispersion and bubble-particle interactions. Quiescent zone helps reducing the probability of recovery of gangue minerals, which may have been entrained mechanically. Therefore

Turbulence modelling for flotation cells based on

Turbulence modelling for cells based on piezoelectric sensor measurement data Jun Meng*1, ... collection rate constant can be related to the size of the turbulence . ... This was resolved by changing the cell aspect ratio and extending the to allow efficient recovery of particles up to 350 μm in size

Up-scaling of froth flotation equipment | TU Delft

Furthermore test work in a laboratory pilot scale cell with adjustable height is discussed, in which the volume fractions of the mixing , and froth can be varied. Combination of these two investigations is expected to allow better understanding of how an industrial cell functions
