Abstract

En hydrometallurgisk fremgangsmåte tilveiebringes for behandling av kob-bermalmer eller konsentrater innbehol-dende gull, ved samtidig å utlute både kobber og gull i en vandig cyanidløs-ning, gjenvinne kobber og gull i metal-lisk form ved elektrolyseseparasjon eller sementering og gjendanne cyanid-ioner.
