An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate.
An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate.
In this study, the influence of different depressants (such as sulfuric acid, phosphoric acid or mixed acid of sulfur acid and phosphorus acid) on the flotation separation performance of an artificial mixture of apatite and dolomite (gangue mineral) was investigated through laboratory flotation tests.
The ore testing Laboratory of 911metallurgist, in the selection of reagents for the flotation of various types of ores, uses that combination which gives the best results, irrespective of manufacturer of the reagents. The data presented on the following tables should be useful in selecting reagents for trials and tests, although new uses, new ...
high-sulfur bauxite is mainly sulfide, containing a small amount of sulfate. It is difficult to remove sulfur sulfate through flotation, so the primary target mineral for desulfitization is pyrite. 2.2. Methods 2.2.1. Flotation test All flotation experiments were performed in a flotation cell (1.5 L, XRF, China), and the agitation speed was ...
Overall, this work proposes for the first time a coadsorption model of DDTC and H2O and provides important insights into interfacial adsorption in high-sulfur residue flotation. Discover the world ...
The flotation experiments were done with bacteria as a depressant for sulfur and mineral matters associated with coal particles. Flotation test was carried out in a Denver flotation cell (D-12) of 1/4 l capacity. Tap water was used throughout the tests.
The desulfurization of high-sulfur bauxite via flotation is more difficult than conventional sulphide, since the finely disseminated sulphide in the high-sulfur bauxite can lead to excessive particle entrainment, increase of froth, and low separation efficiency. ... The flotation test results obviously show that sodium silicate is an effective ...

Additions of three arious dosages of sodium silicate to the sulfur flotation werev tested. Pine oil of 20 g/t and kerosene of 20 g/t were also added in each test. Pulp pH was maintained at about 6. The flotation results are shown in Table II. Table II. The effect of sodium silicate on sulfur flotation. Test No. Sodium silicate, g/t Grade, %
This study aimed to recover cobalt using tailings of the Küre flotation plant, which were determined to contain 0.17% Co. Flotation tests were conducted on samples taken from the tailings to ...
Further, the sulfur content in the fluorite concentrate can be reduced to 0.02% with 91.52% fluorite recovery by single flotation test with 1.7 kg/t renewable collector dosage.

Flotation-hot filtration method 2, 3 is predominant for recycling element sulfur in the high-sulfur residue, due to its simple process, low -cost production and feasible scale- up . Therefore, it ...
The method of the flotation test was the same as that in Section 2.2.1.2 Pure Mineral Flotation, and the collector (IPETC) dosage and pulp pH value are 3 × 10 −5 mol/L and 8.0, respectively.
The raw ore flotation test showed that IPETC displayed superior flotation performance to the elemental sulfur compared with sodium ethyl xanthate () and ammonium dibutyl dithiophosphate (ADDTP) collectors.
The optimal control of sulphur flotation process is difficult due to the unavailability of key process variables, complex process dynamics and the computational complexity in solving …
Fine particles of many sulfide minerals including sulfur itself, and sulfides of copper, are naturally hydrophobic. If they are subjected to flotation soon after grinding they will tend to stick to bubbles and to be raised to a froth. ... The standard flotation test gives good results as far as the quality of coal is within a range and thus ...
In the batch flotation test, the slurry which was ground for 5 min was transferred to the flotation cell. ... which indicated that the butyl xanthate was an efficient collector for pyrite in the flotation of high-sulfur bauxite. 3.5. Open …
Sulfur removal from tungsten concentrates is achieved through reverse flotation. • The pulp pH of reverse−flotation desulfurization process should be lower than 6. • The sulfur content decreases from 4.53% to 1.77% after desulfurization treatment. • The average value of sulfur removal efficiency in the industrial test was 57.19%.
The main mineral composition of HSR includes elemental sulfur, pyrite, plumbojarosite, sphalerite, etc. The toxicity test results show that the leaching concentration of Zn, Cd and Pb in HSR is higher than the identification value. ... 45 μm fraction prior to flotation. This can reduce the adverse effect of fine gangue and plumbojarosite on ...
The sulfur grade and concentrate recovery increased by 11.63 % and 9.10 %, respectively, and the lead and silver recoveries from the tailings increased by 8.72 % and 9.50 %, respectively, compared with those obtained by using a conventional flotation process. These test results indicate that ultrasonic pretreatment is an effective technique for ...
The flotation tests revealed that the sulfur–phosphorus mixed acid could depress the apatite effectively. ... The monomineral flotation test and microcalorimetry were used to study the flotation ...
An efficient flocculation flotation-hot filtration process was developed to recover elemental sulfur and sulfide minerals from a pressure acid leaching residue of zinc sulfide …
Now that we're all educated on sulphide flotation selectivity and its impact on mass-pull; review the 2 rougher flotation test results below and tell me if More Mass is Better?. 3 plots are provided to help in your analysis: Mass VS Copper Recovery | Copper Recovery VS Total Sulfur Recovery | Copper Grade VS Copper Recovery.
