Only one gold extraction method cannot be used to recover gold from all parts of computer. Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors. From CPUs we can recover gold through aqua regia. Pyrolysis and hydrometallurgy are used for gold recovery from computer chips.

This isnt exactly the way to recover gold. However, you can sell the char for a lot of money since it contains gold. Remove all parts of a computer that contain gold and burn them in a large metal barrel. Youll be able to recover only the charred pieces or chars from the ashes since theyre made of metal.
