2019-8-15Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores 4. In this process, pyrrhotite as a primary impurity is separated from iron ore using typically potassium butyl xanthate as the primary collector. The otation process normally
1998-9-12Atomistic simulation techniques were used to investigate the interaction between the minerals calcite and fluorite with water and methanoic acid. The relative adsorption energies suggest that methanoic acid preferentially adsorbs onto fluorite surfaces, while adsorption of water is energetically preferred over methanoic acid on the calcite cleavage plane in agreement with experiment

The further adsorption of sodium oleate reduced the flotation of calcite and achieved the flotation separation of the two minerals. Tian et al . 25 studied the mechanism of action of the inhibitor ethylenediaminetetraacetic acid and the collector sodium lauryl sulfate in the flotation separation of lapis lauli with fluorite and calcite
Flotation reagents and particle sie are also important parts of iron ore flotation. 2.2. Regularity of the interactive effect The flotation efficiency of iron ores is likely to be passive and easily influenced by ore particle sie, which is limited to a narrow particle sie range of feed approximately 10150 m
2017-5-10The flotation experiments were performed using a micro-flotation column 2.5 cm in diameter and 26 cm in height. The total volume of oleate solution was 100 cm3. A flotation time of two minutes was used at a nitrogen flow rate of 70 cm3min. The experiments were repeated three times, and the reported values were the average of
A similar mixture, involving sodium oleate and a fatty alcohol, conducted to an efficient flotation separation of scheelite from calcite Filippov et al., 1993 Filippov and Filippova, 2006. It is assumed that mixing ionic and non-ionic reagents allows to reduce the electrostatic repulsions existing between the ionic groups of anionic
2015-10-19Flotation of calcite at pH 9.7 Semisoluble Salt Flotation Apaptite calcium phosphate is one of the major non-metallic minerals produced by flotation The pc is 6.4 yet as shown below the flotation response with oleate extends well below this pH indicating chemisorption
The mechanism of the formation of the hydrophobic agglomerate in fine scheelite flotation was studied using eta potential measurement, contact angle measurement, optical microscope measurement, and atomic force microscopy AFM colloid probe technology. Zeta potential measurement results confirmed the adsorption of sodium oleate on scheelite, fluorite, and calcite surface and surface
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. An attempt has been made to evaluate the mechanism by which orthophosphate ions depress apatite flotation. Replacement of SO ions on gypsum by HFO ions is found to occur rapidly in solution. The presence of CaHPO
2020-6-26The ero-points-of-charge of apatite, calcite, and fluorite are pH 6.4, 10.8, and 10.0, respectively. Scheelite is negatively charged above at least pH 3. Flotation responses of these minerals in the presence of potassium oleate and sodium silicate are presented and compared with electrokinetic data. Colloidal silica appears to be the species principally responsible for calcite depression
2015-10-19Flotation of calcite with 5x10-4 oleate and 5x10 sodium silicate With fluorite and apatite there is a minor effect, but with scheelite very little effect. The effect with phosphate is shown above for the flotation of phosphate. Starches, etc. These natural products are used widely in industry as depressants. Their
