1. Förfarande för gemensam utvinning av innehället uran, yttrium, torium och sällsynta jordartsmetaller i en organisk fas, kännetecknat av att nämnda organiska fas bringas i kontakt med minst ett utspädningsmedel, som är en eter, alko-hol, polyol, amid, sulfoxid eller keton, minst ett utfäll-ningsmedel, som är ammoniak, ett ammoniumsalt eller en fluo-rid, med undantag av fluorvätesyra, och en vattenfas, varvid utspädningsmedlet valts sä, att en homogen miljö ästadkomms med den organiska fasen och vattenfasen, varvid erhalls en vätskefas och en fällning, som innehaller förutnämnda mineral-arter, som därefter avskiljs frän vätskefasen.

4. Förfarande enligt patentkravet 1, kännetecknat av att utspädningsmedlet är en alkohol eller polyol, speciellt en alifatisk alkohol med kort kedja, som fördelaktigen har mindre än 6 eller 6, närmare sagt mindre än 4 eller 4 kolatomer .
5. Förfarande enligt patentkravet 1, kännetecknat av att utspädningsmedlet är en amid som fördelaktigen har mindre än 6 eller 6 och närmare sagt mindre än 4 eller 4 kolatomer.
6. Förfarande enligt patentkravet 5, kännetecknat av att amiden är dimetylformamid. 16 7560 3

9. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat av att den organiska fasen bringas först i kontakt med utspädningsmedlet och därefter tillsätts utfäll-ningsmedlet.
10. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat av att vatten tillsätts vätskefasen da den organiska fasen bringas i kontakt med utspädningsmedlet och ut-fällningsmedlet eller därefter.
11. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat av att uranet föreligger i den organiska fasen i oxidationsgraden som Vl-värd, det reduceras genom att till-sätta ett reduktionsmedel tili den organiska fasen eller en blandning av den organiska fasen och utspädningsmedlet.
12. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat av att den organiska fasen tillsätts förut-nämnda mineralarter genom att bringa den i kontakt med en vattenfas av en syra som innehäller nämnda arter.
13. Förfarande enligt nägot av de föregäende patentkraven, kännetecknat av att förutnämnda organiska fas innehäller minst ett ämne ur en grupp som bildas av fosfor-, fosfin- och fosfonsyrors alkylestrar, arylestrar och alkylarylestrar.
14. Förfarande enligt nägot av patentkraven 1-2, kännetecknat av att förutnämnda organiska fas innehäller minst ett ämne ur en grupp som bildas av dialkylpyrofosforsyra, dialkyldifosfonsyra och dialkyldifosfinsyra. Il
