| titleOfInvention | Manufacturing method of high purity zinc-nickel ferrite mother liquid and manufacturing method of zinc-nickel ferrite raw material using the mother liquid |
| abstract | The present invention dissolves high-purity waste Ni anode and Zn anode in the steel mill Zn-Ni plating process in the waste acid generated in the cold mill of steel mill and undergoes refining process to produce high-purity Fe, Ni, Zn mixed chloride, and then It is an object of the present invention to provide a method for producing a high purity Zn-Ni ferrite mother liquor by wet or dry treatment and a method for producing a high permeability Zn-Ni ferrite raw material using the mother liquor.n n n The present invention for achieving the above object is a step of washing the waste Ni anode and waste Zn anode generated in the steel mill plating factory, and processing them to polish the chip, the Fe ions and residual hydrochloric acid in the waste acid generated in the steel mill cold rolling mill Adjusting the concentration of the hydrochloric acid so that the molar ratio is 1: 1, by processing 0.5 times more than the number of moles of residual hydrochloric acid Ni chips processed in the waste acid with the concentration adjusted as described above to the molar ratio of Fe: Ni: hydrochloric acid 2 :. adjusting x: 2-2x, and dissolving the molar ratio of Fe: Ni: Zn to 2: x: 1-x by administering a waste Zn positive electrode chip at least 0.5 times the residual hydrochloric acid concentration to the solution, and Fe, Ni, Zn is a high purity Zn- comprising a step of producing a sludge by adjusting the pH in the state in which the Zn chip in the aqueous solution dissolved in 2: x: 1-x, and then aging and stirring it Ni ferrite mother liquor production method and the mother liquor And to the use relates to a method for producing a Zn-Ni ferrite material of the magnetic permeability in the invention. |
