| Research Abstract |
In order to develop rare metal recycling from small domestic appliances(SDAs), the authors applied their scrap sorting technology based on laser 3D analysis to separate mobile phone and digital camera and so on. As the result, it was capable to concentrate Ta by the separation of SDAs according to their kind or year of manufacture. Moreover, preferable grinding or crushing techniques for printed circuit board and Li-ion batteries detached from SDAs were clarified.
