The effect of agitation on the flotation of platinum

2005-7-1  The level of agitation has a profound effect on flotation in mechanical flotation cells. Agitation is responsible for creating a suitable hydrodynamic environment in the cell for efficient gas dispersion, particle suspension and flotation. 2.1. Mechanical agitation

Investigating the effect of energy input on flotation

2008-11-1  There is a considerable body of experimental and theoretical evidence to suggest that energy input (or agitation) plays an important role in improving particle–bubble contacting, particularly in the finer particle size ranges where flotation efficiency is poor (Deglon, 2005). However, determining the effect of energy input on flotation kinetics is problematic as (stirred) flotation cells have complex

"A Study of Effects of Flotation Conditions on

The results showed that flotation efficiency increased with agitation but decreased with increasing consistency. Fiber loss increased with consistency but decreased with increasing agitation. Bubble size showed less effect than consistency and agitation. However, increasing bubble size reduced flotation efficiency and fiber loss.

Effect of agitation on the interaction of coal and

2017-5-15  As can be seen that the recovery-flotation time curves basically overlapped for the agitation speeds from 0 to 1200 rpm, which indicates that the agitation (when rpm < 1200) has very little effect on the pure coal flotation. However, when the agitation speed is over 1200 rpm, the two curves of 1600 and 2000 rpm slightly diverge from the curve of no agitation, showing that the flotation rates of 1600 and

2019-5-15  In Fig. 5a, the effects of different agitation speed on the flocculation/flotation harvesting efficiency were measured.

1 Froth Flotation Fundamental Principles

2009-8-27  1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

"A Study of Effects of Flotation Conditions on

Three variables: (1) consistency, (2) agitation, and (3) bubble size were studied for their effects on flotation efficiency and fiber loss. Flotation was done by using a Hallimond apparatus. The floated and non-floated portions were quantified by image analysis based on number of ink particles and total area of ink. The percent fiber loss was calculated from solids' weights of both portions.
