Abstract
Det beskrives en fremgangsmåte ved elektrokjemisk oppløsning av en svovelinneholdende og/eller kon- sentrert malm inneholdende minst ett metall som skal gjenvinnes, hvilken fremgangsmåte gjør bruk av minst en elektrolysecelle utstyrt med en ione- byttermembran og med anodiske og katodiske rom, hvor en spenningsforskjell blir påført idet frem- gangsmåten omfatter de følgende trinn: a) å oppløse malmen i en uttrekkende elek- trolytt og forårsake elektroavleiring av ett av nevnte minst ene metall som skal gjenvinnes i kato- derommet av nevnte minst ene celle, og b) anodisk oppløsning av en svovelinnehol- dende og/eller konsentrert malm i en elektrolytisk celle med en forskjell i kontrollert spenning, c) å regenerere den uttrekkende elektrolytt i det anodiske rom av nevnte minst ene celle, eller minst en andre celle, og gjeninnføre den således regenererte uttrekningselektrolytt, slik at dens mengde forblir nesten konstant for derved å minima- lisere forbruket av reagensene og energi.
