  • Flotation separation of limonite from calcite with sodium

    Flotation tests show that the recoveries of limonite and calcite are close to 95% within the pH range of 75–100 using 3 × 10 −4 mol/L sodium oleate as collector However, the flotation of limonite was depressed by calcium ions generated from the dissolution of calcite in the flotation of a mixture of limoniteWhile the rising rate of limonite showedatrendofinitialincreaseandfollowingdecreasewith thechangeofthepHvalue,therisingrateoflimonitereached the maximum when the pH value was 79 and the maximum floatation ratio was 176% At pH of 22 and 116, the floata tion ratios were 235% and 325%, respectively, for limoniteThe Flotation Separation of Magnesite and LimoniteLimonite is not a definite mineral, more a rock type It is largely formed from goethite but also contains clays and other impurities Drop in recovery and grade may be attributable to clay adsorption of collector and entrainment of clays in the froth productLimonite in Cu sulphide Ore Froth Flotation (Sulphide

  • Extraction of Iron from Limonite Xinhai

    The flotation process used in the extraction of iron from limonite can adopt positive flotation or reverse flotation process Research and practice show that the reverse flotation is more suitable for the removal of quality and impurity of limonite In addition, the limonite has the loose crystal particle and large specific surface area, whichLimonite is a weak magnetic mineral, as refractory iron ore It doesn’t have obvious differences in density, magnetism, and floatability Limonite has the characteristics of unfixed chemical composition, unstable iron content, a huge change of water content, and easy to overcrush in the crushing and grinding stagelimonite XinhaiThe flotation cell was agitated in a mixing speed 1500 rpm Limonite flotation tests used oleic acid 1000 g /ton and frother pine oil 400 g /t to be conditioned According to the results of the flotation made on pH effect on Limonite at size classed; −0,1 mm grain obtained by gravity concentrated classes test results as given in Figure 3Concentration and Microwave Radiated Reduction of

  • Iron ore Processing Plant

    Limonite flotation process The single flotation method has a good recovery effect for the fine iron minerals, but limonite is easy to slime, which can seriously affect the flotation effect Therefore, the desliming or strengthening slime disperse can be adopted before the flotationThe flotation recovery of bastnaesite was significantly affected by dissolved fluorite and barite species After treatment with fluorite and barite supernatants, the flotation recovery sharply decreased from 6216% to 811% and 2409%, respectively, at pH 3 and from 9000% to 968% and 3961%, respectively, at pH 11 (2)Effect of dissolved fluorite and barite species on theThe flotation cell was agitated in a mixing speed 1500 rpm Limonite flotation tests used oleic acid 1000 g /ton and frother pine oil 400 g /t to be conditioned According to the results of the flotation made on pH effect on Limonite at size classed; −0,1 mm grain obtained by gravity concentrated classes test results as given in Figure 3Concentration and Microwave Radiated Reduction of
