Abstract

Det beskrives en fremgangsmåte for utlutning av et verdimetall fra et basismetallsulfidmalmmateriale omfattende utlutning av malmmaterialet med en liksiviant omfattende et klorid, en oksidant og saltsyre. Utlutningen kontrolleres ved bruk av lave konsentrasjoner av saltsyre og et redokspotensiale for å bevirke dannelsen av hydrogensulfid fra basismetallsulfidmalmmaterialet. Hydrogensulfidet strippes fra utlutningsoppløsningen for derved å redusere mengden sulfat som genereres i utlutningen til meget lave nivåer. Utlutningen kan også gjennomføres for å begrense medoppløsning av platinagruppemetaller og gull sammen med basisverdimetaller. Utlutningen gir et verdimetall anriket utlutet materiale og en fast rest og den faste rest kan deretter utlutes for å gjenvinne platinagruppemetaller og gull. Verdimetallrikt, utlutet materiale kan oksideres og nøytraliseres for å gjenvinne verdibasismetaller. I en utførelsesform er kloridet magnesiumklorid og liksiviantoppløsningen regenerert.
