Coarse particle flotation for early gangue rejection application has attracted considerable attention in the mineral industry. Since grinding units consume a significant amount of energy and sometimes stand as the most energy-consuming unit in the process (Curry et al., 2014, Jeswiet and Szekeres, 2016, Hassanzadeh, 2018), the early …

Froth is an important part of the flotation system. Yet, despite the importance of the froth phase, relatively few studies have been conducted to examine the impact of froth behavior on the performance of conventional and column flotation cells. If the froth phase is not sufficiently stable, mineralized bubbles that enter the froth layer rupture

ABSTRACT Inherent limitation of the mechanical flotation cell is the entrainment of hydrophilic particles (gangue) in the water reporting to the froth. In this study, a combine column and cell flotation process was proposed to reduce the entrainment of gangue particles and, ultimately, ash content of coal flotation concentrate in Datun coal …

A study was developed at Ujina plant, CMDIC, Chile, to evaluate the effect of particle size and liberation on the flotation scale-up factors (Yianatos et al., 2022).The experimental work was developed in an industrial rougher bank of six 300 m 3 cells. Fig. 1 shows that the particle size has a great impact, increasing the scale-up factor from 1.5 …

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.

The RFC is designed to enhance the hydrodynamics of flotation to achieve a significantly more efficient flotation process. These studies have confirmed the potential for this innovative technology to deliver on that promise and offer single-stage cleaning in place of up to ten conventional flotation cells.

Variables of hydrodynamics are equally important as those of surface chemistry in determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro hydrodynamics is responsible for solids suspension and aggregates transport, and micro-turbulence plays an important role in the sub-processes of …
