FIELD OF THE INVENTION

The present invention relates to a recycling apparatus, and particularly to an apparatus for recycling noble metals.

BACKGROUND OF THE INVENTION

With advancement of technologies, the electronics industry develops prosperously. Waste derived from electronic components increases daily. The waste includes integrated circuits, printed circuit board, resistors, or capacitors, and comprising elements of copper, lead, aluminum, iron, and noble metals. If the waste is not recycled and processed appropriately, the environment will be polluted and, from the perspective of fully utilizing the noble metals, it is invisible squander.

The recycling process of waste containing metals is mainly focused on recycling and reusing valuable metals including high-priced noble metals such as gold and palladium. For example, the waste containing gold comes from the integrated circuit industry and the printed circuit board industry. In the processes of thin-film deposition or metallization in the integrated circuit industry, a lot of waste containing gold is produced including replaced molds and derived waste from vapor deposition materials, waste liquid during gold metallization, waste wafers containing gold, gold powder, waste resins containing gold, waste catalyst containing gold, and waste iodine liquid containing gold, etc.

As the electronics industry progresses towards the trend of smaller, thinner, and more efficient, the selection and development of materials is crucial. For example, in the selection of electrode materials for multilayer ceramic capacitors, palladium is usually regarded as the electrode material of choice owing to its superior conductivity and low reactivity at high temperatures. However, because palladium is costly, it is important to recycle and reuse palladium effectively during the development of multilayer materials using palladium alloys.

Currently, there is no apparatus that can recycle noble metals systematically. In most cases, recycling of noble metals is performed manually. The present invention provides an apparatus for recycling noble metals systematically. Thereby, the speed of recycling is enhanced, and the amount of recycled noble metals is increased as well.
