Introduction

King of metallic gold No. 79 is the element with the symbol Au. It is yellow. It is free element in nature and no reactivity. It is resistant to rust or oxide stains. Melting point of gold is 1064 degrees Celsius and boiling point is 2701 degrees Celsius. Specific gravity is 3.19. Atomic weight is 196.67. The crystalline form is cube, Octahedron or Dodecahedron.  Nowadays, the prices are higher. Gold is used as a component of multiple devices. When used, it will expire and it is not useful. How many people know that dropped gold or junk gold. E-Book gold extraction can make the readers know about the gold that can extracted a lump of pure gold > 99 % easily.
The readers just Read and follow this E-Book you will be able to extract the gold from the gold plated,alloy materials in the course.

At Chips Etc. we often get inquires into what is the value of gold found in vintage computer chips and other electronic items. People are often amazed to learn how much precious metal is lost whenever they throw away their old electronic circuit devices. Gold can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics. Although it is possible to melt the gold plating away from the circuitry, you will cause more of a mess and lose some of the precious metal. The most effective way to reclaim gold from scrap components.

Chips, ICs, CPUs and many electronic components contain valuable precious metals that can be recovered. This type of electronic waste accumulates as a waste product during the manufacture of electronic appliances, during the dismantling and recycling of disused appliances and also in the form of overstocks at assembly firms.

Refining of processor chips, ICs, CPUs

The processor (CPU: Central Processing Unit) is the brain of the PC. It contains millions to billions of microscopic transistors and a few hundred gold plated pins. Processors are one of the most value dense portions of the PC. Older processors are generally larger and have more generous gold plating than more modern ones: 386/486 and Pentium chips are particularly valuable. Here are some more details about 486′s.

The processor is recognizable as a large rectangular or square chip that plugs directly into the motherboard. It is usually the largest single chip in the PC. Intel and AMD are the largest PC processor manufacturers, however IBM, ARM, Motorola and others make them as well. The processor often has a heat sink attached to it which may also have a small fan. Heat sinks are typically aluminum, which has little scrap value.

Processors are also found in video cards (there they are called GPUs: Graphics Processing Units), in cellphones, iPods and iPads, and most other electronic devices. Generally only computer processors are large enough and detactable enough to merit separating them. The value of the processor varies greatly depending on the model. As mentioned above, older processors generally have more precious metal content.

Notice the gold dotting this connector board, making it a very valuable (and heavy) piece of equipment to recycle. There’s gold in ordinary cell phones, along with copper and silver, and the gold is easy to extract. Cell phones yield up to 150 grams (15.3 ounces) of gold per ton, compared to five grams per ton of ore, according to Urban Mining.

In terms of e-waste, cell phones hold some of the most valuable bang for the buck. Chock full of bits of gold, silver and copper, cell phones offer easy extraction and reuse of these valuable materials, and with technology rapidly advancing, there is no shortage in sight. Gold, which has rapidly increased in value during the past few years, is of particular interest to companies looking to cash in on e-waste extraction.

The reason for this surplus is simple: Cell phone manufacturers are increasingly turning to gold as a conductor element in their high-tech circuit boards instead of the less conductive copper.
Gold, in particular, is easily extractable in these devices, so much that it is possible to extract more gold per ton of cell phones than per ton of actual ore. Per ton, gold ore yields approximately 5 grams (0.18 ounces) of gold. Per ton of recovered cell phone circuitry, it is possible to yield up to 150 grams (5.3 ounces) of gold.
In turn, jewelers and yes, electronics manufacturers are rapidly trying to get their hands on this re-purposed precious metal, which is typically melted down into its pure state following extraction from the mobile device.

One refinery in Japan is picking apart between 10,000 and 20,000 cell units every month. Another company in Tokyo is melting at least 7,000 ounces of gold per month just from cell phone mining and extraction.
Still, with only 10-20% of cell phone users opting to throw their old devices away, chances are good that a lot of precious metal is hiding in cabinets, drawers and closets around the world.
