Analysis of the flocculation process of fine tailings particles in saltwater through a population balance model
TL;DR: In this paper, a population balance model is used to describe the flocculation of tailings particles in aqueous salt solutions, where synthetic tailings, composed of quartz and kaolin particles, are flocculated in a jar at a constant shear rate where in-situ FBRM determines the size of the aggregates.

Study on the effects of pre-conditioning time on the floatability of molybdenite from the perspective of cavitation threshold
TL;DR: In this paper, an acoustic method called high-intensity focused ultrasound was applied to detect the nuclei in a molybdenite suspension before and after long-duration pre-conditioning.

Effect of whisker aspect ratio on the density and fracture toughness of SiC whisker-reinforced Si3N4
P. R. Sneary,Z. Yeh,M. J. Crimp +2 more
TL;DR: In this paper, ball milling was combined with ultrasonic dispersion of the composite suspension to reduce the aspect ratio from 25 to 15, resulting in an increase in the green and sintered density, along with the fracture toughness.

A mass conservative approach to model the ultrasonic de-agglomeration of ZnO nanoparticle suspension in water
TL;DR: In this paper, the authors deal with the non conservation of volume during ultrasonic breakage of ZnO particles whose density varies against size and calculate the energy released by the collapse of the cavitation bubbles.

Collapse of an initially spherical vapour cavity in the neighbourhood of a solid boundary
TL;DR: In this paper, a numerical method was proposed to solve the problem of balloon bubble collapse near a plane solid wall, using finite time steps and an iterative technique for applying the boundary conditions at infinity directly to the liquid at a finite distance from the free surface.

Cavitation produced by Ultrasonics
B E Noltingk,E A Neppiras +1 more
TL;DR: In this article, the problem of cavitation produced by ultrasonic vibration is examined theoretically, and it is predicted that all cavitation phenomena will diminish and finally disappear as the frequency is raised.

Agglomerate and Particle Size Effects on Sintering Yttria‐Stabilized Zirconia
TL;DR: In this article, the initial-, intermediate-, and final-stage sintering of fine crystallite yttria-stabilized zirconia was studied, and it was found that agglomerates limit attainable green density, interfere with the development of microstructure, impede initial-stage Sintering kinetics, and limit the potential benefit of the fine crystallites on final stage sinterings.
