5. Metod enligt patentkrav 1, kännetecknad därav, att i flotationssteget tillförs i slammet en lämplig reducerande kemikalie för att reglera 30 redox-potentialen tili den önskade nivan.
6. Metod enligt patentkrav 1, kännetecknad därav, att till flotationssteget tillförs en inert gas för att reglera redox-potentialen till den önskade nivan.
7. Metod enligt patentkrav 1, kännetecknad därav, att till flotationssteget tillförs en gasblandning, väri en del är inert gas och en del är luft.
8. Metod enligt patentkrav 1, kännetecknad därav, att ätminstone en del av gasen som avlägsnas ur flotationssteget äterförs till flotationen. 10
9. Metod enligt patentkrav 1, kännetecknad därav, att ätminstone en del av det i flotationssteget bildade metallhaltiga flotationskoncentratet äterförs tili sulfideringen.
10. Metod enligt patentkrav 9, kännetecknad därav, att 10 - 30% av det i flotationssteget bildade metallhaltiga flotationskoncentratet äterförs tili sulfideringssteget.
11. Metod enligt patentkrav 1, kännetecknad därav, att värdefulla 20 mineralernas flotation utförs i ett steg.
12. Metod enligt patentkrav 1, kännetecknad därav, att mängden av sulfidjoner som tillförs sulfideringssteget är stökiometrisk i förhällande tili mängden av silver och bly i slammet. 25
13. Metod enligt patentkrav 1 eller 12, kännetecknad därav, att sulfidjonerna leds tili lösningen genom att använda ätminstone en kemikalie ur gruppen Na2S, NaHS, Ca(HS)2 och H2S.
14. Metod enligt patentkrav 1, kännetecknad därav, att pH regleras inom omrädet 1-4.
