1. Förfarande för lösningsmedelsextraktion av en metall ur en vattenhaltig sulfatlösning innehällande kal-5 cium i en väsentligen mättningsmängd genom att bringa den vattenheltiga lösningen motströms i minst tvä steg i kon-takt med ett organiskt extraktionsmedel, vilket förmär att extrahera bäda nämnda metall och kalcium, men vilket Sr väsentligen selektivt tili metallen visavi kalcium, 10 kännetecknat därav, att minimering av gips i nägot som heist av stegen omfattar minimering av kontak-ten mellan extraktionsmedlet och den vattenhaltiga lösningen efter det att metallen extraharats väsentligen full-ständigt ur den vattenhaltiga sulfatlösningen. 15 2. Förfarande för selektiv extraktion av en metall ur av sulfathaltig vattenfas motströms i flera blandings-steg med en Ström av en organisk fas i närvaro av en mättningsmängd av kalciumjoner upplösta i den sulfathaltiga vattenfasen, kännetecknat därav, att 20 a) vätejonen i den organiska komponenten utbytes mot metallen i vattenfasen för att införliva metallen i den organiska fasen, b) vattenfasens pH-värde justeras i steget för be-gynnelseblandande av den obelastade organiska strömmen med 25 den uttömda vattenhaltiga strömmen, eller närä detta steg, tili ett första pH-värde, vilket tilläter extraktion av metallen men minimerar extraktion av kalcium i den organiska fasen, och pH hälles vid det justerade värdet, och c) vattenfasens pH justeras i blandningssteget med-30 ströms med hänseende tili den organiska fasen tili ett pH- värde, vilket skiljer sig frän det första pH-värdet, och pH hälles vid det justerade värdet, för att maximera extraktion av metallen i den organiska strömmen, varvid övermätting av vattenfasen med kalciumsulfat i nägot som 35 heist av extraktionsstegen förhindras. 15 8061 0
3. Förfarande enligt patentkravet 2, känne-t e c k n a t därav, att den metall, vilken skall extra-heras selektivt, utgöres av kobolt.
4. Förfarande enligt patentkravet 3, känne-5 tecknat därav, att kobolt extraheras selektivt ur en nickelhaltig lösning.
5. Förfarande enligt patentkravet 2, känne-tecknat därav, att den organiska komponenten omfat-tar en fosfinsyra med formeln 10 Ri 0 Ri 0 \/ \/
15. P /\ /\ R2/ OH R2 °H 20 i vilka formler R1 och R2 oberoende av varandra betecknar alkyl som kan vara substituerad, cykloalkyl, alkoxialkyl, alkylcykloalkyl, aryl, alkylaryl, aralkyl eller cykloal-kylaryl. 25 6. Förfarande enligt patentkravet 5, känne- tecknat därav, att den organiska komponenten utgöres av di(2,4,4-trimetylpentyl)fosfinsyra upplöst i ett kolvätelösningsmedel.
