The use of amine reagents in combination with ultra fine kaolin results in a . at this point with Amine 3305 from Clariant was used as a collector and frother in 187;More detailed
Flotigam EDA is an ether mono amine used as a collector of silicates such as quartz, micas and feldspar and it is the most widely used collector in reverse hematite ore otation.
Separation of amine insoluble species by otation with nano and Flotigam EDA 3B (Clariant ), were prepared using deionized water (reverse osmosis) and used throughout the work. This reagent is a cationic Flotation studies were carried out using the same setup shown as in
and Flotigam EDA) and two ammonium quaternary salts (cetylp iridinium choride and cetyltrimetylammonium bromide) are ef cient as collector of both, kaolinite and quartz, however the span of time required to oat kaolinite was approximately 510 times longer than that necessary to oat quartz (depending on the collec tor type).
The flotation behavior of pure quartz studied by Sahoo et al. indicated that cetyl pyridinium bromide and benzyl dimethyl tetradecyl ammonium chloride were more effective than the conventional cationic collector DDA and CTAB . Flotigam EDA 3 (ROCH 2 CH 2 CNH 2) and Flotigan 2835 2L (RO(CH 2) 3 NH(CH 2) 3 NH 2
an amine acetate type collector, Flotigam CA, was found as the most effective collector. At the favorable flotation conditions, the ash of the oil shale was reduced from 34.76% to 16.81% at 84.10% combustible recovery. Flotation results after ultrasonic pre treatment of the oil shale at different power levels are given in Figure 4. At 20 and
With unacceptably high silica content characteristics, magnetite mined from the deposits require a reverse flotation process using a proprietary collector developed by Clariant Mining Services to produce a commercially attractive product.
The processes of iron ore flotation being either by means of mechanical cells or columns, are fed by parti cles whose sizes vary 10 and 150 181;m, the ultrafine parti cles (slimes) are removed by means of cyclone, for they affect the process in a negative way, and the top size is
The processes for iron ore concentration that stand out are the gravitational methods, magnetic separation, and flotation. And among these, flotation has allowed the concentration of low grade ore fines. Flotation is a procedure that began to be applied in the mineral industry in the early twentieth
Environmental impact of an etheramine utilized as flotation collector Antonio Peres1, Netra Agarwal2, Nilson Bartalini 2, The results led to the conclusions that the collector Flotigam EDA utilized in degree at the expense of the flotation performance. Flotigam EDA is an etheramine with dodecyl radical and neutralization
charges for flotation tests. Flotigam EDA 3 (Clariant), an ether monoamine, and Flotigam 2835 2L (Clariant), an ether diamine, were used as . 18 Mark Ma . et al. Role of Water Structure Making/Breaking Ions in the Cationic Flotation of as a collector . Figure 4. Flotation
Flotation depressants are used to inhibit the adsorption of the collector onto the surfaces of the minerals, when its flotation is not desired, thus, enhancing the effect of collectors on the capture of a desired mineral. Fig. 8 shows the results of the microflotation tests for quartz using Flotigam EDA 174; as collector in a nanoemulsion
A pretty clean and relatively easy to treat ore was tested suggesting a collector optimization strategy would probably yield only relatively minor incremental metallurgical improvements. Therefore, collector suite fine tuning was deemed largely better left for future optimization, possibly when the plant is in operation. In earlier studies Sumitomo had adopted the use of thionocarbamate Cytec
In these systems, the collector was composed by alkyl ether monoamine (Flotigam EDA 174;), n butyl alcohol, and kerosene. Corn starch with a high degree of purity was the depressant in the process. Corn starch with a high degree of purity was the depressant in the process.
The flotation circuit makes use of the rougher, scavenger and first 2 stages of cleaners to produce a final concentrate. Sulphuric acid is added to the flotation feed to adjust pH to 2.5 and then a collector (Flotigam EDA) is added into a conditioning tank.

Generation of nanobubbles The bubbles were generated by depressurizing air saturated water solutions at a high ow velocity through a steel needle valve (2 mm internal diameter Globo 012 Santi174;) into an empty glass column (50 cm high; 2 cm inner diameter).

of FLOTIGAM EDA as collector. Then, the pH was reduced to 2.5 with HF and 600gt covite,1 of AERO 3030C collector were added to enable the feldspar otation. Chemical assaying, using an UNICAM M series atomic absorption spectrome ter (AAS) and a WDS X ray uorescence Philips PW 2404 spectrometer (XRF) were performed. 3 Results and discussion
the conventional method where flotigam EDA was used as the collector reagent, palm oil was successfully used as a substitute collector reagent in the froth flotation of the iron ore, with highest concentration gotten at a pH of 10; thereby being the best pH for the flotation ofthe ore.
Jan 02, 20190183;32;Floatigam EDA Finds Application in Hematite Extraction. Flotigam EDA is widely used in the mining industry for effective flotation, on the terms of differential surface properties of the various minerals present in the mixture. Flotigam is usually applied to separate of
Solutions (2500 mg L 1) of a commercial amine Flotigam EDA 3B (Clariant ), were prepared using deionized water (reverse osmosis) and used throughout the work. This reagent is a cationic decyl trimethyl ether amine with molecular weight of 195 g mol 1
verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy droxides. The most used reagents are amine and corn starch, which act respectively as collector and depressant [1 4].
