How to Extract, Separate Refine Gold scrap. Archimedes Channel posted a video to playlist How to recycle gold — feeling excited in USA.
I am planning to extract gold from the PCB scrap. So I have to strip gold electroplated on the PCB. Like other miner, we are going to use a NaCN solution to strip gold. Some months ago, I had a chance of watching a leaching work by using a NaCN solution in a certain plant.
· Gold extraction in this process, gold uses to make AR need more purity 75% because if less than 75% purity, the precipitation of sodium sulfite is not incomplete. Gold is gone and water is not pure. AR is increasing the percentage of gold or made of pure gold > 99%. Fill Hydrochloric acid into Nitric acid.
· Recycling gold from jewelry or electronic scraps—think computer chips and circuits lined with thin layers of gold—is not without issue either. Annually, Foley explained, the world produces more than 50 million tons of electronic waste per year; that amount is increasing rapidly due to nonstop innovation that shortens the life span of electronic devices.
· I receive a lot of scrap electronics, among the scrap I have 40,000 gold plated phono connectors, I would like to recover the gold however electrolysis would involve connecting each of the 40,000 connectors to an anode ? this would take a lot of time, I would prefer to submerge in a solution all the connectors at once. is there a step by step process to reclaim the gold ? your help would be ...
