New Way to target

 I'd love to know what chemicals they are using...

Researchers at the University of Edinburgh are developing a new compound to extract gold from used electronics. Around 7% of the world’s gold is inside e-scrap, of which less than one-third is currently salvaged, according to project leader Professor Jason Love.

One tonne of gold ore contains around up to 5 grams of pure gold. However, a tonne of discarded mobile phones easily holds 300 grams of the valuable metal, Love says. The chemical reagent pioneered by in Edinburgh effectively recovers ‘a very high purity of gold’ from various types of discarded electronics.

First, the researchers place the printed circuit boards in a mild acid to dissolve metallic parts. An oily liquid containing the new reagent is then added, which allows gold to be extracted selectively from the complex mixture of metals found inside electronics.

Any ideas for this please comment  - have a great day :-)

Gold Recovery: How to recover gold from ink cartridges

Another excellent video from "Moose Scrapper" on how to recover gold from ink cartridges.

Some ribbons have adhesive on one side and will not work in this reaction. You may have to incinerate them with your IC's and flat packs. Very easy process with HCL ( Muriatic acid) and bleach to make Auric chloride.

Gold finger boards..

An excellent Video created by  Moose Scrapper - some great tips..

Muriatic acid is one of the names for hydrochloric acid. It is also known as spirits of salt or acidum salis. "Muriatic" means "pertaining to brine or salt". The chemical formula for muriatic acid is HCl. 

I want to try the tip of using stainless steel to extract the copper from solution :-)
