Title:ResearchonFlotationSeparationofCarbon-SulfideMineralsinHigh-SalinityWater
Abstract:
Theflotationseparationofcarbon-sulfidemineralshasbecomeachallengingtaskduetothecomplexityoftheirsurfacepropertiesandtheinterferenceofhigh-salinitywater.Thispaperaimstoreviewrecentstudiesontheflotationseparationofcarbon-sulfidemineralsinhigh-salinitywater.Itdiscussesthemechanismsinvolvedintheflotationprocess,theinfluencingfactors,andthestrategiesemployedtoimprovetheflotationperformance.Thefindingshighlighttheimportanceofoptimizingtheflotationreagents,adjustingthepH,controllingthepulpdensity,andemployingadvancedflotationmethodstoachieveeffectiveseparation.Additionally,thechallengesandperspectivesinthisfieldareexploredforfutureresearch.
