Abstract:Thegoldore beneficiationandmetallrgical wastewatercontainscyanide,heavymetals,andrecalcitrantorganic compounds,with complex composition,strong toxicityand poorbiodegradability.Basedonitspolltion characteristics, the multi-stage coupledsystemisconstructed withthecoreofqualityseparationanddiversion,cyanideoxidation,heavy metal precipitation,airflotationseparation,filtration,deepoxidationand membranecrystallzation.Throughparameter optimizationandunitintegration,theclasificationreductionofpolutantsandstablecontrolofwaterqualityareachieved, forminga closed-loop technical system covering source control,processtreatmentandenduse reuse,and providing engineering support for theresource utilization and near zero discharge of goldore beneficiation and metallurgical wastewater.
