How to Recover Gold from Computer Parts-Ram Gold Fingers | Gold Recovery from Computer Parts

When we say computer parts, we mean motherboards, RAMs, hard drives, add-on cards, processors, power supplies, fans, monitors, etc. Today, we will discuss gold recovery from rams' gold fingers. Gold fingers are the gold-plated columns you see along the connecting edges of printed circuit boards (PCBs). Aqua regia can be used to recover gold from gold fingers. Cut off the gold fingers from the PCBs. Prepare Aqua Regia; it is one part nitric acid and three parts hydrochloric acid. Put the golden fingers into the heat-resistant glass beaker and pour aqua regia onto them till they are completely immersed in the solution. The aqua regia will dissolve both copper and gold. The gold is coated with a layer of copper. Give it some time to dissolve all the gold. Separate the solution from the PCB pieces, then filter it. Neutralise the solution with urea. Precipitate gold with sodium metabisulfite (SMB). If you have an inquiry about something, you can write to us using the contact form available on our blog. Warning!
