— To recover gold in the laboratory experiment, the team salvaged the electronic motherboards from 20 old computer motherboards and extracted the metal parts. They dissolved these parts in an acid bath so as to ionize the metals. How the gold is recovered: Gold ions adhere to a sponge of protein fibrils.

 — Pulling gold out of e-waste suddenly becomes super-profitable. A new method for recovering high-purity gold from discarded electronics is paying back US$50 for every dollar spent,...

 — Recovering gold from junk electronics, also called urban mining, may be profitable if you can amass large volumes of electronic waste (e-waste), particularly computer parts. It may not be worth the ordeal to extract gold from a …

In this article, I will show you how to get gold from computer parts without chemicals. There are other ways to do it but using common materials is by far the safest method. So, let's get started.

There are basically two methods of melting gold flakes and dust to recover gold available to the average person, the mercury method called Gold-Mercury Amalgam with its obviously toxic by-products and the Borax Method.

 — The article then walks through the process step-by-step: disassembling devices, cleaning printed circuit boards (PCBs), creating an etching solution with cyanide, submerging PCBs to dissolve gold foils, filtering out the foils, and properly disposing of …

 — Researchers at University of Saskatchewan in Canada have found a cheap, fast, and environmentally-friendly way to extract gold from materials while producing re-usable waste — a technology that might have potential to turn e-waste to gold, literally.

There are two widely used extraction methods for gold recovery from electronics. The first uses mixed hydrochloric nitric acids to dissolve the gold for recovery and further hazardous chemicals to extract pure gold from the acids. Toxic fumes are released during the process.

 — Selective recovery of gold from electronic waste using mild reagents is a challenge. Now a photocatalytic technology is reported to enable highly selective gold dissolution through solvent pH...

 — Look no further! In this article, we'll explore some methods for extracting gold from electronic devices without using chemicals. With a few simple tools and techniques, you can recover gold and other precious metals from electronic waste and turn it into a profit. Let's get started! Contents show.
