METHOD FOR REMOVING IMPURITY ELEMENT OF MAGNESIUM FROM SOLUTION CONTAINING NICKEL |
摘要 |
Provided is a method for removing an impurity element of magnesium including: a hydroxylation step of adding an alkali hydroxide to the nickel-containing solution in the production process to form a hydroxylated slurry; a carbonation step of adding an alkali carbonate to the hydroxylated slurry to form a carbonated slurry, and recovering nickel component from the solution; a solid-liquid separation step for the slurry thus obtained; and a neutralization step of subjecting a solution after reaction obtained by solid-liquid separation to a neutralization, and recovering an impurity element included in the nickel-containing solution in the production process. |
