Problems solved by technology
[0002] The pins and other parts of many memory cards contain a small amount of gold. It would be wasteful to throw away waste memory cards without recycling. However, the current method of extracting gold from memory cards is mainly by dissolving and extracting gold in aqua regia, but aqua regia contains a lot of gold. Strong corrosiveness, improper operation will cause personal safety and pollute the environment, and the steps during extraction are cumbersome, and it is very troublesome to operate manually. A device for extracting gold from a batch of waste memory cards described in the present invention can solve the above problems

The invention discloses a device for extracting gold from waste and used memory cards in batches, comprising a recovery box, a working cavity is arranged in the recovery box, a feeding port is provided on the upper wall of the working cavity in communication, and the working cavity is A rotating drum is rotatably connected to the lower wall, an inner cavity is arranged in the rotating drum, and a main shaft is rotatably connected to the upper wall of the working cavity. The present invention can automatically extract the gold in the waste memory card, so as to facilitate and quicken the resources When extracting, use aqua regia to dissolve the gold in the memory card, then separate the dissolving solution from the memory card waste, and then add sodium sulfate to the dissolving solution to precipitate gold, the whole process does not require manual operation, is safe and environmentally friendly, and can It is very convenient and quick to process waste memory cards in batches.
Description
technical field [0001] The invention relates to the related field of memory cards, in particular to a device for extracting gold from waste memory cards in batches. Background technique [0002] The pins and other parts of many memory cards will contain a small amount of gold, and throwing away the used memory cards without recycling will cause waste. However, the current method of extracting gold in memory cards is mainly by dissolving and extracting aqua regia, but aqua regia contains a large amount of gold. Strong corrosiveness, improper operation will cause personal safety and environmental pollution, and the steps during extraction are cumbersome and very troublesome to operate manually. A device for extracting gold from a batch of waste memory cards described in the present invention can solve the above problems. . SUMMARY OF THE INVENTION [0003] In order to solve the above problems, a device for extracting gold from a batch of waste and used memory cards is desig...
