Silver Anvil has processed computers for the last 2 decades. We used to use a power chisel to remove the gold bearing components from the boards and then discard the depopulated boards to the trash. When the EPA classified computer boards that were trashed as a hazardous waste, we found that it was more economical to prepare the boards by removing the non-precious metal bearing items and shipping the prepared boards to a third-party for metal recovery. In this way, we obtain credit for silver, gold, platinum group metals, and copper.
Today we are receiving computer residue, paying for its gold content, preparing it, and shipping to a third-party. If quantities of gold-plated material are present, they are stripped using the technology defined in the section about Gold and Silver processing.
We also receive generic electronics, for a toll fee, and strip it for contained metals which are recycled through our metals broker.
