This is due to them having gold plated heat spreaders, and the amount of gold plated pins found on the underside of these CPU's, and smaller package size (less ceramic material used in the CPU's packaging per pound). Also, the Intel Pentium Pro Processor remains a top CPU desired by gold recyclers. It's gold contents are one of the highest of any mainstream CPU package from the 1990's to date, mostly
Gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
This opens a big opportunity for canny gold investors to acquire a raw source of industrial gold at a fraction of the value of the gold contained in these CPU’s. These CPU’s can be found in dumped computers on the side of the road, at the local tip and are often given away for free at garage sales. The CPU’s can be divided into three classes:

Gold refining. This refers to processes used to processes used to extract and separate the precious metals in mined material, doré, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create
Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric
Mar 09, 2010· The density of gold is 19.3 gcm-3 and this relies on its atomic mass as well as its crystal structure. This makes gold quite heavy than certain other common materials. For instance, aluminum’s density is 2.7 gcm-3 and steel’s density is just 7.87 gcm-3. Melting and Boiling Points of Gold. Pure gold has a melting point of 1064 °C.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
Jul 20, 2001· Gold is used as a plating material, where sodium gold cyanide [NaAu(CN) 2] is used as a gold plating solution. The plating has good chemical resistance and electrical properties, however the plating lacks wear resistance, in which case gold-indium plate is utilised. Gold alloys also have a number of applications such as:
Mar 01, 2016· That was fascinating in its own right, but now the DIY chemist has but his metallurgical know-how to what seems like a slightly more practical purpose: ripping the gold off old, useless computer
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.
Working or not the computer is still valuable and not just for the copper, tin or steel it contains. Many scrappers do not know what parts in a computer are gold and as a result, they throw it away or leave it by the curb with the other trash. Finding gold to sell is not an easy task.

Collect any gold-containing metal scraps to which you have access, including jewelry, computer processors, old telephone wiring or gold tooth crowns. Keep in mind that outdated electronics are likelier to produce parts with a high enough level of gold to make the procedure worthwhile. This is the gold I collected in a bucket over three months.
