How to recycle gold from cpu computer scrap

 

Recycling gold from computer scrap can be a profitable endeavor, and it can also help to conserve natural resources. Here are some steps you can follow to recycle gold from computer CPUs (central processing units):

1. Collect old computers or CPUs that are no longer in use. You can also purchase CPUs from electronics recyclers or salvage companies.

2. Disassemble the CPUs to separate the various components. This typically involves removing the CPU from the motherboard and taking apart the heat sink.

3. Sort the components by type, such as metal, plastic, and glass.

4. Remove any gold-plated components, such as connectors, using a hammer and chisel or a chemical process called cyanidation.

5. Melt the gold-plated components using a furnace or torch. This will allow you to separate the gold from any other metals that may be mixed in.

6. Purify the gold using a refining process, such as the Aqua Regia method. This involves mixing hydrochloric and nitric acids to create a corrosive solution that can dissolve the gold.

7. Pour the purified gold into ingot molds and let it cool and solidify. The resulting ingots can then be sold to a refiner or precious metal dealer.

It's important to note that recycling gold from computer scrap can be a complex and potentially dangerous process, as it involves the use of chemicals and high temperatures. If you're not familiar with these processes, it's best to seek the help of a professional or use a service that specializes in gold recovery.
