When the flotation density of the mineral, the material particles are larger, the use of thick pulp. When the flotation density is small, the mineral of fine grain and slime material is used thinner pulp. To meet the froth flotation requirements, the concentration of pulp can be adjusted by adding the required water and flotation agents.
Figure 6.12 shows measured pulp density profiles in an industrial thickener operating normally and in an overloaded condition. The measured profile during normal operation agrees with that expected in an ideal thickener and the gradual increase in the pulp concentration between the lower conjugate concentrate C M and the discharge concentration C D is clearly evident.
2. Flotation Characterizations: Pulp and Froth 2.1. The Pulp Zone The effect of solids in the pulp zone will be determined from measurements of bubble size distribution and gas hold-up. There is little literature on either relevant to flotation systems and that is contradictory. For instance, measurement of .
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
3.2 Effect of pH on flotation Maintaining PAX and MIBC concentrations at 100 g/t and 200 g/t, respectively, flotation behav-iour of Cu and Mo was investigated at varying slurry pH ranging from pH 3 to 11 and the results obtained are presented in Table 3 and Fig. 3. Pulp density was maintained at 20% and flotation was
May 27, 2020· Pulp and froth phases. 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 phase recovery presumably improves because ...

After the iron ore is fed to the froth flotation system and the iron ore pulp is obtained. This pulp is analysed with the sample size of the pulp being 171kg/m^3 density and the chemical component of the ore being manipulated to 100 PH. The silica concentrate that is .
size, pulp density and temperature) (Klimpel., 1995). It is possible, in froth flotation, to realize that the particle size distribution influences both the physics of a process by controlling the collision mechanism between particles and bubbles, and the degree of liberation (Machado Leite, 1992).
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 .
Jul 21, 2020· Start following Metallurgy's Linkedin page to get a free (my used) copy of: Froth Flotation: A Century of Innovation. by Maurice C. This thorough volume describes state-of-the-art research and practice in mineral froth flotation as known and practiced a century after its introduction.
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.
Effect Of Pulp Density In Froth Flotation. The froth and the pulphe rate of flotation, keeping the variables constants, varies with the flotation time using the analogy between chemical reactions and flotation processes, this approach is defined as flotation kinetic and is described as follows 2 where c f is the concentration of the floatable minerals in the pulp.
To relate the flotation operation condition with flotation performance, Jampana et al. revealed that the increase in pulp level causes concentrate grade to decrease, as the variation of pulp level has great effect on the froth retention time in the flotation cell . The continuous decrease of froth retention time can lead to less collision time ...
The froth flotation process will be affected by many factors, like slurry concentration, flotation time, and slurry temperature. But these factors can be adjusted to improve the flotation effect. Let's talk about the specific effects of slurry concentration, flotation time, and slurry temperature on froth flotation .
Coal Flotation | SpringerLink. Coal flotation is characterized by the chemical and petro-graphical composition of coal and its rank. In addition, size and sp . gr. of coal particles, pulp density, rate and uniformity of feed, conditioning, type of reagents, pH, presence of clay and type of flotation machines are the other variables which influence the coal flotation.
The impeller in a mechanical flotation tank plays a key role in keeping particles in suspension, dispersing and breaking-up air bubbles, and promoting.
Apr 25, 2014· Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.
Paper/Pulp Froth Flotation. Froth flotation is one of the processes used to create new paper from recycled paper. Known as de-inking in the paper and pulp industry, this process is used to remove hydrophobic contaminants from the recycled paper. The contaminants are mainly comprised of ink and adhesive residue.
Froth Flotation About 3.6 kg of the ore mixture ground 55% passing 75 µm was weighed into a 8 litre Denver cell and mixed with water to obtain a pulp relative density of 1.29. The pulp was dosed with 180 g/t SIBX collector at 40% strength and conditioned with the pulp for 2 minutes. The Sendep 30D at 80 g/t was added as a depressant and ...
Sep 24, 2018· Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulfide minerals . This process is based on the wettability of copper mineral particles to recover the mineral species of interest and depress unwanted gangue. ... Similar results showing the effect of pulp density on the grade ...
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.
