Lorsqu'il est prêt à recevoir le signal modulé par une technique de modulation de phase différentielle pi, le nombre de calculs requis pour calculer le métrique de transition d'état est réduit de manière significative.
Patent CA-2098638-A1 (CA)
Inventor: NYMAN BROR G
IPC: C22B3/04
Filed: 1993-06-17
Abstract: The present  invention relates to a method  for preventing  the  formation  of  jarosite  and  ammonium-  and alkali-based double salts in the solvent extraction of acidic extraction processes.   The organic extraction solution is neutralized  by  ammonium  or  alkali  salts  prior  to  the separation  of  valuable  metals  in  order  to  improve  the extraction recovery.   In a pre-extraction step after the neutralization, the extraction agent is contacted with an aqueous  solution  containing  a  metal  which  replaces  the ammonium or alkali ions contained in the extraction solution. Thus  the  ammonium  or  alkali  ions  are  removed  from the extraction circuit prior to separation of the valuable metals by extraction.
