How to Extract Gold From Electronics : 11 Steps (with ...

Although this method of gold extraction calls for household chemicals, that doesn't mean they are safe. Please be advised that you must handle these chemicals with care. Goggles, gloves, glass apparatus and a very well ventilated room with a fume hood (and a gas mask/respirator are needed as well) or an outside area is highly recommended. After this experiment is over, I will show you how to ...

Simple extraction of gold from e-waste - News - The ...

RESEARCHERS in the UK and the US have discovered that a simple, non-toxic amide can extract gold selectively from electronic waste. Though found in only very small quantities, the concentration of gold in electronic waste, such as computers and mobile phones, is 80 times higher than that found in natural gold ore. In fact, electronic waste is thought to contain as much as 7% of the world’s ...

How to Extract the Gold From Computer Circuit Boards

12/04/2017  Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets, the precious metals remain trapped in piles of waste. There’s about 0.2 grams (0.007 ounces) of gold in a typical mobile phone handset. Recovery of this gold requires knowledge of basic chemistry and considerable care.

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with ...
