Gold extraction technology is based on several procedures that have long been used by many people. You can also get gold yourself at home. We will analyze everything in order.
1
You can extract gold from new or used radio components. Surely you have at home there are electrical chips, diodes, contacts, transistors, clusses of hours, relays and other similar elements. The uninitiated people consider this garbage, and experts on the extraction of precious metals specifically acquire these details for funny money. The technique of Soviet production may be up to 10% of gold. Previously, it was often used in the manufacture of similar products.

To understand how much gold is in products, check out the documents of technology. This information will be useful to you in order to calculate the required amount of solutions. Unfortunately, information on the content of metals is not always valid. But documents of domestic equipment contain only reliable information, so you can safely trust them. Disassemble parts to minimum parts to leave the product element with a maximum gold concentration. You must have a portion of 1-3 g. Before the work, it is well ventilated. Be sure to use the mask, bathrobe, glasses and gloves.

To get gold, prepare "royal vodka". This solution is a mixture of nitric and hydrochloric acid in a 3: 1 ratio. Make the mixture and heat it up to 70-80 degrees. After that, take one billet with the content of gold and place it in the cooked mixture. Technical details contain a lot of copper, so most likely the mixture is painted in green with a dark shade. You need to evaporate it until the amount of water decreases by 2 times. Also in products there is an iron that forms a brown sediment. To dissolve it, pour into a mixture 2 ml of hydrochloric acid.

Then add homework saline to the solution (0.2 g per 10 ml). All this time, the container must be heated. Pour into it a small amount of boiling water and 2 ml of hydrochloric acid. Thus, you can remove from your mixture the residues of nitric acid so that the precious metal evaporates either on the iota.
5
Add a 0.5% hydroquinone solution (1 ml per 100 ml) and withstand the mixture for 4 hours. From time to time stir her. The remaining sediment is filtering by using a dense filter. Then rinse it with a small amount of hydrochloric acid. Cut the drying and make the melting of the sediment (at a temperature of 1,100 degrees or more). Machine under the layer of borants so that gold evaporates. Then, cool it and separate from the layer of frozen borants.
6
Remember that the turnover of precious and non-ferrous metals in private hands without appropriate licensing is prosecuted by law. To get the right to mining gold (even at home), it is necessary to be a subject of entrepreneurial activity. Explore legislationwhich regulates this scope of activity. If you act legally, you can implement the obtained metals. There are many companies that are engaged in the buying of gold, broken jewelry, ingots, etc. You can also contact the pawnshop.
As you can see, it is not necessary to have deep knowledge in the field of chemistry to extract gold. Just follow the above stages in order and follow the safety technique. To the last item, it is serious, since harm can be obtained even if the acid vapor is inhaled.
