Abstract

Fremgangsmåte som gjør det mulig å eliminere forurensninger fra waelz-oksyd (fundamentalt klor, natrium, kalium, svovel og fluor), ved hydrometallurgisk behandling i følgende trinn: Utluting med natriumkarbonat i varmt, vandig, alkalisk miljø; faststoff/væske-separasjon av avløpet og det faste materiale; - rensing av avløpet ved eliminering av tungmetallene og eventuelt de uønskede anioner; vasking med vann av det faste materiale som blir oppnådd etter natriumutlutingen; faststoff/væske-separasjon av vannet og det rensede waelz-oksyd; resirkulering og oppvarming av avløpet som er oppnådd fra vasketrinnet, for gjenbruk i natriumutlutingstrinnet.
