I also want to remind readers of the criminal liability that existed at the time of writing these lines for the amateur mining of precious metals from industrial waste. This arrangement of things can not last for a long time, the principle: "Let it be better for anybody, than for someone" - is flawed. Nevertheless, you can not argue with the Criminal Code. Even precious metals, lost for decades back, can not be considered in the status of finding treasures, if they are extracted from waste. Have to be patient or to act under the aegis of a government undertaking.

With the modern technology of melting gold, many possible variants of its losses are taken into account. Nevertheless, here is a message from the UPI agency, October 1991 : "A resident of Philadelphia wanted to buy a metal roof of an old church." The rulers took only four thousand dollars from an eccentric. But he did not lose money: he extracted eight kilograms of pure gold from tin. The fact that there was a mint next door, from whose pipes, along with smoke, particles of gold were also deposited on this roof . "

The current location of mints as well as enterprises for fusing gold into ingots is not recommended to disclose, so we will touch on old similar enterprises.

Until 1990 , the privilege of melting gold in refined ingots had in Siberia also in the Urals only gold-alloy laboratories. Subsequently, the highest permission was possible to create small gold mines with compulsory registration with the mountain police officer, so that documents on the location of these are melting in the archives should be preserved.

Volumes of metal melted in ingots in the largest gold-smelting laboratories (Tomsk and Irkutsk in addition to Yekaterinburg) were not a state secret in those days, but they were published in newspapers. Here, for example, the figures showing how much also in what place was melted the gold mined in 1899 :

1. Tomsk gold-smelting laboratory - 339 poods.

2. Irkutsk gold-smelting laboratory - 1386 poods.

3. Ekaterinburg gold-smelting laboratory - 641 poods.

From the same reports, the difference between the weight of incoming sand and the obtained purified gold is also seen - this figure varies between 1-2% . Of course, an impressive proportion of these percentages refer to remote impurities, but with such a volume of work, you can imagine how much it flew into the pipe, literally, gold along with the smoke and the hot steam! At that time, there was no word on the purification filters - everything flew in the wind, gold settled somewhere nearby.

Of course, it was a very long time ago, but why not try to compare natural factors, the historical data is also a real change of terrain close to the former gold-smelting laboratory? Then, at what time there will be a belief in luck, you can make some simple quantitative parsing about the concentration of gold in the surface layer, make a technological scheme based on materials that the occupation will have to own, and also connect some state institution or an official face on the basis of an advantageous legal agreement for you.

In my opinion, it would be appropriate to mention here the biogeochemical method of searching for gold as if it were the most suitable for detecting a cluster of tiny gold that settles from the ejection of the gold-smelting pipe. Even in the last century, we noticed the regularity of the appearance of gold in the ashes of trees with its presence in the soil of their growth. I met a message on this topic in the "Bulletin of gold industry" for 1901 . In the modern monograph by A. Kovalevskaya "Biogeochemical methods of prospecting gold ore deposits" practical recommendations are also given on the application of this method. Here are just some excerpts from this work. The main advantage of this method is that a solitary seeker does not need deep pit holes and ditches to take a sample of soil, but it is possible to determine on the surface of the ground the presence of precious metal in the soil. The depth of the definition is the depth of penetration of the root system; for permafrost soils it is 1 -2 m , in the forest zone of loose soils - from 2 to 10 m , but in steppe forest-steppe zones it reaches 60 m . Gold does not accumulate in all plants, and not in all its parts. Here is what the creator of labor writes about this: "The significant essence of gold in relation to the background is found in the bark of pine, birch in addition to larch, in the land parts of legumes additionally sedge, but similar in the live mass of moss-lichen cover. upper part of the cortical layer " . This means of searching for gold is especially good in that gold in the ash of plants is found only directly above the deposit. To search for placer large gold biogeochemical method is not suitable: it is applicable only for those cases when gold is in a crushed state. The collected ash of plants undergoes traditional spectrochemical or neutron-activation analysis. The mass of the sample for the main case is taken to be 10-20 g , and for the other, 0.1-0.3 g of ash is sufficient.

If you manage to get a brickwork of the gold-smelting laboratory pipe into processing, or you find the room where the smelting bricks of the smelting furnace were thrown out, consider that you found a full-fledged treasure. In this case, you can certainly do without the factory equipment. Plovdiv copper smelters can serve as an example. They processed a thousand tons of old refractory brick, using the flotation method, also received about 4 kg of gold . Now calculate almost how much gold can be received from the lining of gold-smelting furnaces? Wash, the figure will be staggering! It is possible that this happy thought has already come to someone's bright head, and the "storerooms" have already been cleaned, but we think that this has not been done carefully everywhere.
