SEPARATING DOLOMITE FROM PHOSPHATE ROCK BY REACTIVE ...

5 Efforts to concentrate high-dolomite Florida phosphate ores by flotation, using conventional fatty-acid/fuel-oil flotation [Liewellyn, 1982], showed that sodium silicate depression on dolomite was not enough to obtain a concentrate less than 1 % MgO. This may be due to the presence of silica in this ore in addition to dolomite.

Fine particle flotation for Florida dolomitic phosphate ...

tank flotation cell and 2-in ID packed flotation column aiming at achieving a phosphate concentrate containing more than 30% P2O5 and less than 1.0% MgO contents at high P2O5 recovery. The characteristics of fatty acid collector, FA-12 and a newly developed PA-31 collector were evaluated for frothability and dolomite flotation rate.

Development of Reagent Schemes for Reducing MgO Content in ...

Successful methods include adding a dolomite depressant in the rougher flotation, dolomite flotation on the cleaner concentrate with grinding, and scrubbing the cleaner concentrate in quartz sand. These techniques could reduce MgO content in the final concentrate by 20-40%.

Dolomite (CaMg(CO 3) 2) which is one of the most common and typical carbonate gangues, often coexists with rhodochrosite, smithsonite, magnesite, and pyrite [5,6,7,8,9,10].A great quantity of dolomite enters into magnesite concentrate easily in the flotation process, thus affecting the grade of the concentrate and causing problems for the downstream smelting process.

10. The concentrate is reconditioned (30 seconds) with sulfuric acid (maintains pH 4-5). This is followed by flotation to remove dolomite. Final processing involves cationic flotation of the fine silica from the dewatered dolomite flotation cell. Resulting phosphate concentrate contained ~ 28% P 2 O 5, ~ 1% MgO and 2.9% insolubles.
