| Abstract: | The disposal process for waste high-temperature Ni-Co alloys was decided by experimental study.The flow sheet was: alkali roast;leaching by NaOH solution;leaching by chlorine;removing iron by TBP solvent extraction;removing chromium by hydrolyzing;removing other impurities by P204 solvent extraction;separating nickel and cobalt by N235 solvent extraction.This paper focuses on purification process of leaching liquid from waste high-temperature Ni-Co alloys.The optimum technical conditions of purificating on leaching solution have been determined through pilot studies.The impurity elements in leaching solution can be removed effectively by adopting conditions of purification process,the solution components fit for requirements of producing nickel and cobalt products after treating solution. |
