Modeling of Bubble Formation and DolomiteParticle Separation.....96 Blockage of the Acid Simplified flowsheet for CLDRI dolomite flotation..13 21. Strategic plan to achieve Zeta potential of apatite in dolomite supernatant before/after PVA adsorption
Flotation of dolomite was observed but flotation of apatite did not occur. 4C Oleic Acid Adsorption Tests Infrared spectra of apatite and dolomite samples on which oleic acid had been adsorbed in the pH interval from to are shown in Figures 12, 13, 1 4 and 15. 38 Series 1 Oleic Acid Adsorption on Apatite Powder Refer to Figure 12 H
When the current deposits in Central Florida are depleted, the replacement production will come from the southern extension of the current mining district. The major problem in the production of fertilizers from the phosphate rock mined in the southern extension is the presence of dolomitic impurity, usually reported as weight percent MgO. MgO content of the currently produced phosphate rock
Conventional flotation scheme is not successful for separation of dolomite from its mixture with apatite. Several processing methods utilizing both anionic and cationic collectors have been proposed to solve this problem, but they have yet to be tested on a commercial scale.
Froth flotation is widely used as an effective method for separating apatite from dolomite. However, it is of difficulty to realize the efficient separation of apatite and dolomite using the
#0183;#32;Flotation separation of apatite and dolomite is very difficult using NaOl alone. PAMS is selectively adsorbed onto dolomite due to its strong bonding to Mg sites. The adsorption of NaOl onto dolomite is hindered strongly by the addition of PAMS. Greater amounts of NaOl is adsorbed on apatite than dolomite in the presence of PAMS.
flotation of dolomite from apatite. An attemp t has been made to evaluate the mechanism by which orthophosphat ione s depres s apatite flotation. 22 Replacement of SO^ ion ons gypsum by HFO^ ion is s found to occur rapidly in solution. Th presence e of CPO^* 211^0 o n gypsum surface iss shown using infrare reflectancd spectroscopye .
Separation of dolomite from phosphate minerals by flotation with a new amphoteric surfactant as collector August 2001 Mineral Processing and Extractive Metallurgy IMM Transactions section C 110(2
The separation of apatite and dolomite is studied,In basic medium,theresult of separation of the two minerals depends not only on the depressantsused but also on the structure of flotation apatite canbe effectively separated from dolomite with a rejection ratio up to 98%,butsedimentary apatite and dolomite cannot be efficiently separated frcm acid
#0183;#32;Efficient flotation separation of apatite from dolomite can be realized by P (AAAMPS). P (AAAMPS) is an ecofriendly and efficient depressant of the dolomite flotation. Much more adsorption of P (AAAMPS) occurs onto dolomite than apatite. The preadsorption of P (AAAMPS) prevents strongly NaOl adsorption onto dolomite.

The selective flotation separation of the carbonate and phosphate from siliceous constituents of the matrix at various pH levels and collector dosages are dis cussed ning electron microscopy revealed that it consisted of apatite, dolomite, feldspar, and quartz (Fig. 1). The apatite was brown to black and occurred as smooth
Flotation of dolomite was observed but flotation of apatite did not occur. 4C Oleic Acid Adsorption Tests Infrared spectra of apatite and dolomite samples on which oleic acid had been adsorbed in the pH interval from to are shown in Figures 12, 13, 1 4 and 15. 38 Series 1 Oleic Acid Adsorption on Apatite Powder Refer to Figure 12 H^ SO^ System Analysis of the 5x differential spectra
Flotation of Dolomite from Apatite. selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite. Further, the selective depression mechanism of NaPP was studied through zeta potential measurements, contact angle measurements, and Xray photoelectron spectroscopy (XPS) analysis.
Abstract:In this study, the effect of sodium pyrophosphate (NaPP) on the separation of apatite from. dolomite by flotation was systematically investigated. Flotation results revealed that NaPP could. selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite.
