So with printed circuit boards, its pretty easy to see where the gold resides. Its not quite as easy to spot the value in the ceramic integrated circuit (IC) chips that are found in computers, especially in the form of large central processing units.
THE CHEMISTRY OF THE EXTRACTION OF GOLD necessary to take this argument a step further. In general, whether the oxidation of gold to the complex AuL; or AuL+ occurs in the presence of The simple ions tend to react in solution to replace the water molecules by stronger ligands. Similarly, if AuCl3 is dissolved in water,
Information on how to extract gold from rock, Extracting gold from rock Crushing the gold bearing rock is not as simple as it sounds. We can't just hit it with a hammer because pieces will fly everywhere and we may lose some of our gold. What we need is a very strong container and bash plate.
