| titleOfInvention | SOLVENT EXTRACTION PROCESS IN THE PRESENCE OF THIOCYANATE IONS |
| abstract | A solvent extraction process using thiocyanate ions to separate two metals contained in an aqueous solution. A mineral acid is added to the aqueous solution to substantially suppress the ionization of thiocyanate ions and to form thiocyanic acid, and the aqueous solution is contacted with an organic solvent to extract the thiocyanic acid, thereby minimizes thiocyanate ion losses. The figure is a diagram of a process for the separation of cobalt and nickel in which: the charge 1 undergoes in 2 an extraction of cobalt by an organic solvent containing thiocyanate ions; the extractant loaded with cobalt is washed in 6 to remove the nickel then is sent to 9 for the back extraction of the cobalt in the form of the salt of the mineral acid while the extractant passes in 16 where it removes the thiocyanate ions contained in the refined product containing nickel from the cobalt extraction step |
