Title:StudyonFactorsInfluencingtheSeparationofSilicon-bearingPhasesinTitaniumConcentrateRe-election
Abstract:
Titaniumconcentrateisacriticalsourceoftitaniumdioxide,usedinvariousindustriessuchaspaint,ceramics,andcosmetics.However,thepresenceofsilicon-bearingphasesintitaniumconcentratesaffectstheirpurityandquality.Inthisstudy,weinvestigatethefactorsthatinfluencetheseparationandre-electionofsilicon-bearingphasesintitaniumconcentrate.
Introduction:
Titaniumconcentrate,derivedfromnaturalores,oftencontainsimpuritiessuchassilicon-bearingphases.Thepresenceoftheseimpuritiescanreducethequalityandpurityoftitaniumdioxide,affectingitsperformanceindifferentapplications.There-electionprocessiscommonlyusedtoseparatesilicon-bearingphasesfromtitaniumconcentrate,ensuringahighpurityoftitaniumdioxide.Thisstudyaimstoidentifyandanalyzethefactorsthataffecttheefficiencyandeffectivenessofthere-electionprocess.
Methodology:
Toinvestigatethefactorsinfluencingtheseparationofsilicon-bearingphases,aseriesofexperimentswereconducted.Titaniumconcentratesampleswithdifferentmineralcompositionsandimpuritylevelsweretakenforanalysis.Thesamplesweresubjectedtovariousre-electiontechniques,suchasgravityseparation,flotation,andmagneticseparation.Theseparationefficiencyandpurityoftitaniumdioxidewereevaluatedforeachmethod,alongwiththeinfluenceoffactorssuchasparticlesize,reagentdosage,pulpdensity,andpH.
Results:
Theexperimentalresultsrevealedthatthepresenceofsilicon-bearingphasessignificantlyaffectedtheseparationefficiencyoftitaniumconcentrate.Theparticlesizeoftheconcentrategreatlyinfluencedtheefficiencyofthere-electionprocess,withfinerparticlesachievingbetterseparation.Additionally,anoptimalreagentdosagewasidentified,asbothinsufficientandexcessivedosagesresultedinreducedseparationefficiency.PulpdensityandpHlevelswerefoundtohaveamoderateinfluenceontheseparationprocess.HigherpulpdensitiesandacidicpHwerefavorableforseparation,whileextremeconditionshadadiminishingeffect.
