As the solubility product of calcium oleate is bigger, the floatability of dolomite which compared to magnesite is much higher in the flotation system of sodium oleate. After the flotation experiments of pure minerals, a novel flotation system for recovering magnesite concentrate from low-grade magnesite ore was developed.
Aug 01, 1996 The results of bench-scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect of water hardness, in addition to other parameters,
Dolomite mining process is the solution of separating dolomite concentrate from Dolomite raw ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences, we applying Dolomite mining process of two-stage crushing, washing, then three-stage separating, flotation . More
The flotation of apatite and dolomite in orthophosphate solution. Creator. Johnston, David Lawrence. Publisher. University of British Columbia. Date Issued. 1969. Description. A study has been conducted on the loss of phosphate ions and excessive oleic acid consumption encountered in the selective flotation of dolomite from apatite.
Whilst the installation is similar to that used for pre-oxidation or Aachen assisted leaching in the Leachox process the flotation concentrate is pumped through the reactor multiple times perhaps as many as 30 passes in contrast to 1-2 passes for the pre-oxidation role .Depending upon the mineralogy ultrafine grinding of the flotation concentrate may be required prior to cyanidation
mineral flotation of apatite and dolomite are illustrated in Figure 26. It is clear from the data that apatite flotation could be achieved with approximately one half of the sodium oleate concentration needed for dolomite flotation. It is indicated from Figure 26 that separation of the two minerals-4
Sep 01, 2020 Moreover, the selectivity index SI was used to evaluate the impact of PAMS on the separation features of apatite and dolomite by direct flotation, and its calculation formula is expressed as follows Cao et al., 2019b 1 SI C A T A T D C D where SI is the selectivity index C A and C D express the apatite and dolomite recoveries in concentrate, respectively T A and T D represent the apatite and dolomite
Aug 10, 2017 Closed-circuit reverse flotation tests using GOFA as the collector resulted in an excellent concentrate with 28.46 wt P 2 O 5 and 0.65 wt MgO, corresponding to a P 2 O 5 recovery of 87.2. GOFA was demonstrated to exhibit outstanding selectivity for dolomite in the reverse flotation of collophanite ore.
A- Flotation Testing Laboratory comparison of five phosphate-dolomite-silica flotation separation processes, developed by various investigators, was completed using a 26 P 2 O 5 2 MgO Florida pebble phosphate supplied by IMCF as the test sample. The current test results were compared with the previous investigators reported results ...
Dolomite mining process is the solution of separating dolomite concentrate from Dolomite raw ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences, we applying Dolomite mining process of two-stage crushing, washing, then three-stage separating, flotation process will be used to process Dolomite with complex structures.
This is followed by f lotation to remove dolomite. Final processing involves cationic flotation of the fine silica from the dewatered dolomite flotation cell. Resulting p hosphate concentrate contained 28 P 2 O 5 1 MgO and 2.9 i nsolubles. Overall recovery of the process is estimated to be around 35.7.
Florida is currently one of the largest phosphate producers in the world. Unfortunately, the phosphate industry in Florida is suffering from depletion of the phosphate-rich ore. Dolomite, however, is a major impurity in the ores. The presence of MgO,
oleic acid, a phosphate concentrate containing 0.89 MgO with a P 2 O 5 recovery of 75 was obtained from the phosphate ore containing 2.2 MgO. Keywords flotation, cellulose, cellophane, dolomite, oleic acid Introduction The phosphateoleic acid flotation system has been studied extensively since the beginning of the flotation reached.

Low grade magnesite coexisting with dolomite was purified by flotation. A process of reverse flotation to remove silicate minerals- positive flotation to concentrate magnesite was explored after the systematic process mineralogical investigation. Influence of different conditions such as grinding fineness experiment, collector experiment and combined modifiers experiment was also investigated.
Aug 21, 2019 Under the optimum flotation conditions 0.1 amylase and 5 10 4 moldm 3 M oleic acid, phospho-concentrate assaying 27.85 P 2 O 5, 0.61 MgO, and 13.14 SiO 2 with a P 2 O 5 recovery of 55.45, was finally obtained, without the use of expensive depressants, e.g., phosphoric acid or sodium silicate, from the phosphate ore containing 18.78 ...
The XRD analysis of the flotation concentrate indicates that the content of abundant carbonate minerals of dolomite significantly reduces the AS ratio in the concentrate. As these minerals react with hydrochloric acid Reddy et al., 1999, the hydrochloric acid leaching of the concentrate was carried out, to improve its Al 2 O 3
The calcitedolomite in actual practice is recovered using fatty acid as a collector and starch or dextrin as the pyrochlore depressant during calcitedolomite flotation. A number of studies have been conducted 1,2 in which different fatty acid modifica-tions were examined. High selectivity and high calcitedolomite recoveries were obtained
Apr 12, 2016 Calcite is activated and floated into the froth concentrate while the sericite, quartz, and other silicates are depressed and rejected into the flotation tailing. The froth from the last 2 or 3 cells of the Sub-A calcite flotation circuit may be recycled, if desired to maintain grade and provide a final refuse low in calcite.
recoveries with acceptable concentrate grades in single stage flotation of sedimentary phosphate rock. Thus, the commonly used phosphate flota tion process in Florida is the double float process, viz. anionic flotation of phosphate min erals at alkaline pH, rougher flotation, followed by acid scrubbing and cationic reverse flota
Apr 23, 2020 Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the minerals.The ...
