How is the gold production in the home? Try to understand the article.
From what we can get the gold?
Get precious metal house can be of the conventional electronic components, which are practically in every apartment. They can be found in older phones, laptops, computers and other equipment. When collecting electronic components note the chip transistors and connectors, parts of which are coated with gold. Get gold in the home are not easy, because to extract more or less decent amount of metal it takes a lot of details.
Particularly enterprising craftsmen organize a business to extract the precious metal. The scheme is simple: collect a large amount of detail, and then extract the gold home. In the 90th, some of the older parts smelted from the receivers and televisions whole bars. So how to find the old technique is problematic, but to get a small amount of gold is still possible.
Before you begin the procedures to chemical refining of metal, you need to collect a sufficient amount of the feedstock. This includes transistors, chips, old connectors, relays,
radio tubes, diodes, indicators, leds, processors, sockets and contacts motherboard. The volume of gold produced at home will depend on the type of parts: the older the computer, TV or radio.
Also plated products suitable for receiving the yellow metal: watch cases, bracelets, cutlery. The entire production process. from which you got this or that element, the more it gold.
As preliminary work, many craftsmen at first to sort the available raw material at their disposal. All the items are divided into two large groups new and old parts. The pile of the old well tolerated brazed products.
Then the sorting within these two groups. In each group, separated by rich and poor in content elements. At this stage, the feedstock is maximum release of unnecessary parts, in which gold is absent.
Why is it important? When mine gold at home, there is a question of reducing the consumption of reagents and reducing the time for the whole process, so the more spare parts we remove, the more the save on costs so.
Final sorting is done with a magnet the elements are divided into those of the magnet and the magnet. As a result, after sorting, you will have several piles of parts, each of which can be processed separately.
Regardless of the type of parts, refining of precious metals is carried out by etching the house. The basis of the method is the inertia of the noble metal. Gold does not react with other chemical elements, otherwise metal nuggets in nature have not met. All the notable exception to this rule is the dissolution of gold in the "reagent", which is a mixture of two concentrated solutions. Hydrochloric acid is mixed with nitrogen in a ratio of one to three.
The resulting mixture should be colorless, but later changes color to yellow. "Reagent" has an unpleasant pungent smell characteristic of nitrogen and chlorine. The solution is certainly prepared immediately before use, as over time it will decrease the quality of oxidation.
Suitable for the deposition of precious metal is one of the following reagents: hydrazine, oxalic acid, hydrogen peroxide, sulfite or sodium pyrosulfite, iron sulfate. The most commonly used is the last. After carrying out all the necessary procedures, Gold will swim in solution thin slices, like flakes of foil. To get them, you need to filter the solution through a thick cloth, allowing to separate even small particles of metal.
Gold in the home should be removed with the help of high-quality reagents, otherwise you or it does not work, or the cost of etching will exceed the final output of the precious metal. All reagents must be of good quality and not spoiled, utensils for the reaction of aluminum or enameled.
The efficiency of extraction of gold component of electronic components will depend on the pre-treatment of raw materials from unnecessary parts. Organic components can be removed through calcination, the others to remove by mechanical means. If the device contains iron, it is possible to remove the remains after all the procedures with the help of a magnet.
It is also important to remember that when we extract gold at home, we do it for self own benefit, but not to the detriment of your health. Work should only be in a special form, which protects your skin and the respiratory tract from exposure to chemicals.
