| Outline of Final Research Achievements |
The magnetic separation technology to collect a nickel ingredient was studied
and developed the study at which recycling of rare metal resources, reduction in processing waste fluid and a longer life of plating liquid are aimed, which was put into effect from the plating waste fluid, which is discharged from the electroless nickel plating process used for auto parts and an electronic component. Because a obtained nickel-sulfate crystal recycles the nickel-phosphate ion generated by a plating reaction, which has magnetism, we can separate this by the magnetic field and reuse as a raw material in the plating process.
