METHOD FOR FABRICATING RAW MATERIALS OF NICKEL-COPPER-ZINC FERRITE UTILIZING SPENT RESOURCES

摘要

PURPOSE: A method for fabricating raw materials of Ni-Cu-Zn ferrite is provided to reduce a fabricating cost of raw materials of Ni-Cu-Zn by improving a fabricating method. CONSTITUTION: A high Ni solution or a high Zn solution is fabricated by mixing a spent Ni anode and a spent Zn anode with hydrochloric acid in a plating mill. Each pH of a spent Fe solution or a spent Cu solution is controlled and a filtering process for the spent Fe solution or the spent Cu solution is performed. The ferrite composition mixed solution is formed by diluting and mixing the Ni solution, the Zn solution, the Fe solution, and the Cu solution. The pH of the ferrite composition mixed solution is elevated by adding alkali thereto. The filtering process and a purification process for the ferrite composition mixed solution are performed. The pH of the purified solution is elevated by adding alkali thereto. Hydroxide is dipped into the purified solution. The hydroxide is mixed with solvent in order to form granules of Ni-Cu-Zn ferrite. The raw materials of (Ni-Cu-Zn)OFe2O3 are fabricated by performing an annealing process.
