Welcome to the forum. Extracting(refining) gold, silver etc is not what is discussed on this forum. The is another forum which specializes in this, Gold Refining Forum, which I highly recommend for this information. If you go there please do yourself a big favor and read the required section first and then read more before asking questions, it's just how that forum works.
To educate yourself here go to section for electronics and start reading threads. At the bottom of each thread are recommended similar threads.
For additional education on identifying electronics go to the scrap buyers/sellers section(there is a button at the top of each page of the forum). Several of the buyers threads have photos of scrap.
Here's a great one:

Lastly work on finding companies that will buy your
ewaste and don't go down the refining route. 73, Mike
