| titleOfInvention | Method for the treatment of mixed hydroxide product produced in a metal extraction process |
| abstract | A method for the treatment of mixed hydroxide product (MHP) (10) produced in a metal extraction process such as a nickel extraction process. The method comprises the steps of treating the MHP (10) with a first acid solution (12) at a pH in the range of 4 to 8 as a first redissolution step (14) and separating a first liquor (16) formed in the first redissolution step (14) from a first residue (18) formed in this step. The method further comprises the step of treating the first residue (18) with a second acid solution (20) at a pH in the range of 0.5 to 4 as a second redissolution step (22). In this way, the impurities in the MHP may be selectively removed in the two redissolution steps. |
