When all is said and done, Cody was about to get about a third of a gram of gold-ish metal out of the parts you see above, and even that third of a gram did not look especially pure.
Article Summary X. To remove gold from circuit boards, start by purchasing concentrated nitric acid from an industrial or chemical store. You’ll also need a face mask, safety glasses, and industrial gloves to work with nitric acid, since it can harm your skin and eyes and cause nausea if it’s inhaled.

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
Start by obtaining as many scrap electronics components to reclaim gold from. Generally speaking, older electronics work better because enhanced manufacturing processes use less gold than older electronics, so an old 386 or 486 computer, for example, contains more gold than a modern computer.
Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts and electronics. Some people find it profitable to attempt to extract the gold from these scraps, then refine and sell it.
Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
The removal of gold plating from jewelry is often desirable if the gold surface has become tarnished or lackluster. In most cases it will not be possible to preserve the gold as it is removed. Gold plating is very thin, usually over a silver or copper base, and the process will typically destroy the thin layer of gold as it is removed.
For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
This extraction process involves the chemical reaction between the pulverized e-waste and sodium cyanide, which produces a soluble gold cyanide solution that allows for easier extraction of the precious metal 3. While useful, gold cyanidation remains a controversial technique that is prohibited in several countries around the world.
The primary methods used to extract minerals from the ground are: Underground miningSurface open pit miningPlacer mining The lo ion and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

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.
Mining is a technical field and requires a comprehension of many complex factors. This includes everything from the characteristics of an orebody to the actual extraction method envisioned and used—and the devil is often found in these technical details.
Many gold coins, like those made before 1947 in the United Kingdom, contain silver to make them harder. This is something a coin professional will have to tell you, as the gold quality and content depends on the type of coin. Many coins, like sovereigns and Krugerrands, are made from 22-carat gold and can be valuable as scrap gold.
