Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.
Chemicals Used in Mining Hesperian Health Guides
Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaverite, sylvanite, nagyagite, petzite and krennerite.
#0183;#32;Cyanide is used to separate gold from ore. In its pure form, cyanide has no color and smells like bitter almonds. It may lose this smell when it combines with other chemicals. It can be used in powder, liquid, or gas forms.
In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straightforward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. This process is not supposed to be lucrative.
#0183;#32;them to extract the metal. The oxides of less reactive metals, such as iron, form less stable oxides and other compounds. Relatively little energy is needed to reduce them to extract the metal. So

#0183;#32;Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is
Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.
In this reaction, the iron (III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide. In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to...

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
Dimethylglyoxime is a chemical compound described by the formula CH 3 C (NOH)C (NOH)CH 3. Its chemical formula is C 4 H 8 N 2 O 2. It is an off white fine powder but if you purchase low quality then it can be solids. Many companies are manufacturing DMG but I recommend you RDH or fluka.
Use Chemicals To Extract Gold From Computer Parts. Gold cyanidation also known as the cyanide process or the macarthurforrest process is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex it is the most commonly used leaching process for gold extraction
#0183;#32;The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if youre able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it''s hazardous to both your health and the environment to use them. Method 1
The first is pyrometallurgy, which burns the gold off using high temperatures. This method is energy intensive, cost prohibitive and releases dangerous gases, like dioxins.
