2019年5月21日 froth rheology change was not yet clear [27]. A more viscous pulp may result in a more stable froth [28]. Li et al. has exclusively investigated the froth rheology and its effect on flotation performance in recent years [21, 29-31].They have observed correlation between froth viscosity and mineral recovery in froth flotation process. Figure 5.
A Brief Review of Pulp and Froth Rheology in Mineral
2020年2月8日 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 , a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic
Effects of Operating Parameters on the Froth and
2021年5月7日 The effects of flotation operation parameters, including froth depth, air flowrate, and frother dosage, on the froth and collection zone recovery and the flowrate of particles into the froth phase were investigated in a 10 m3 industrial cell. The results showed that froth recovery increases upon increasing air flowrate and frother dosage, as well as
Study on surface physical and chemical mechanism of
2023年3月3日 The particle size distribution of UFG and FFG samples were analyzed using a laser particle size analyzer BT-9300S (Bettersize Instrument Ltd., Dandong, China) and the results are shown in Fig. 1.It can be seen from Fig. 1 that the values of d 50, d 90 and d 95 were 40 μm, 93 μm and 116 μm, respectively for the UFG sample and 60 μm, 160 μm
The Critical Role of Pulp Density on Flotation Separation
2018年7月26日 In this study, the effect of pulp density on the separation of nickel-copper sulfide ore and serpentine was examined. The rheological measurements of both minerals and artificially mixed Micro-flotation tests were conducted on a XFGC flotation machine with a 40 mL cell at 1608 rpm (revolutions per minute). Before the mixed mineral fl
Control of clay minerals effect in flotation. A review
flotation performance and ore quality the negative effect of the clay minerals on flotation should be identified. The presence of clay minerals leads to problems, such as changing the froth stability, which are related to swelling behaviour, increase in pulp viscosity, overconsumption of reagents, slime coating and mechanical entrainment.
The effect of conditioning on Froth Flotation
2020年12月8日 Effect of Collector Concentration and Pulp Density -Varying concentration and pulp density led to some unexpected findings. The collector used in most of the tests was found to ionise only weakly and hence the reaction rate constant was adversely affected by increasing collector doses. The partial ionisation also resulted in the total lack of
