Effect Of Pulp Density In Froth Flotation

Results of this testwork have shown that the pulp density does affect key parameters of the flotation process in both the pulp and froth phases. Pulp phase kinetic rates decrease at high density

The results show that in the pulp zone there is no effect of solids on bubble size and gas holdup; in the froth zone, although hydrophilic particles solely do not effect on the water overflow rate

May 27, 2020 Results of test work have shown that the pulp density affects key parameters of the flotation process in both the pulp and froth phases (Runge et al, 2012). One of the findings was that froth phase recovery presumably improves because of a stabilising effect due to a greater loading of solids on bubble surfaces

flotation rate, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995). This makes it

Mar 12, 2016 Effect of Flotation Density on Grade and Recovery Grade of concentrate is, in general, improved by decrease in the percentage of solids in the pulp, and such improvement may be accompanied by improvement in recovery, but continued decrease in percentage of solids eventually results in decrease in recovery

The effect of flotation feed density on metallurgical performance has been investigated. Results of test work have shown that the pulp density affects key parameters of the flotation process in both the pulp and froth phases (Runge et al., 2012). One of the findings was that froth

The results revealed that rheology, which is caused by pulp density, played a key role in flotation performance. The decline in density (from 40 wt % to 20 wt %) increased the nickel and copper recoveries from 70.7% to 79.5% and 82% to 85.4% respectively in the artificial mixture (1:1)

were then separately added, and the pulp was conditioned for 2 min with each reagent. Distilled water was added to the test periodically to maintain the pulp level. The flotation time was fixed for 3 min at room temperature (25 C). The froth and sink products

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation

The observed effect of flotation operating conditions and particle properties on water recovery at laboratory scale. Minerals Engineering, 94: 83–93. Wang, L., Runge, K., Peng, Y., and Vos, F., 2016. An empirical model for the degree of entrainment in froth flotation based on particle size and density

of the particles attached at the pulp-froth interface, is often used to measure the performance of the froth phase (Yianatos et al., 2008). This approach focuses on the overall behaviour of the froth, which is used for modelling in flotation plants. The concept of froth

Nov 01, 2019 There are many factors influencing the effect of froth flotation technology, including grinding fineness, pulp density, pulp acidity, reagent system, aeration and agitation, flotation time, water quality and slurry temperature. Here you'll learn more about the details and related solutions. Let's dive in now! 1. Grinding Fineness Before Flotation

Apr 30, 2012 The effects of operating conditions such as the froth depth, air flow rate, impeller speed, and pulp density on desulphurization of MT have been investigated. This study indicates that all of these parameters have effects on the flotation kinetics, recovery of sulphur and concentrate grade

Introduction The froth phase plays an important role in the recovery of minerals and the produc-tion of concentrates in the flotation process. The flotation zone includes two parts of col-lection (pulp) and froth zone, and the perfor mance of each section can be considered sep
