There's many youtube videos on how to recover gold, its fairly straight forward if you know some chemistry have a modest size lab and can handle a lot of nasty chemicals.  It needs enough scale to setup an operation, though obviously this is going to be orders of magnitude less than a mining operation.  A friend works at local scrap yard that has invested in shop/plant to process electronics on site to recover gold.  Surprised it works for copper too, though the yard does strip cabling, breaks and sorts electrical stuff to separate ferrous, circuit boards and miscellaneous for further processing.
