How is gold mined in Kolyma

Modern job search is as automated as possible; gold is washed in with special dredges or with the help of mobile factories. However, in the last century, mankind mined precious metal by hand. It was a hard work, which worked mostly prisoners.

About its complexity, I can say responsibly, because he himself tried to wash gold in the old manner. Looking ahead to say that the attempt was a success. However, alas, I could not get rich. What happened and where did the mined gold read under the cut ...

Practically everywhere, where we drove and saw the river, we found uneven sections. These are the consequences of the extraction of precious metal (river water in this process is an important component):
In some places, the upper gold-bearing layer of the earth was simply removed, in others everything was dug out beyond recognition. A typical picture: the washed rock is piled up and cast as it is:
So, how does mining take place? We will talk about mining in the open way.There is also mine, but, as a rule, it is not used in the Kolyma.
On the panorama of the site where they are looking for gold. The center of the entire site on the right, where the car is. She washes the entire breed, which is collected in a career and sent by pipe to the factory:
The tractor drives along the bottom of the quarry and rakes layer after layer of rock to the car. The grass grows in the distance - it is a natural layer of the earth, by which one can estimate how deeply the gold miners have sunk:
There, where the rock falls, there is a hose with high pressure water. The stones are separated by a net, then the remaining soil with gold is sent through pipes to the factory, where the next stages of filtration await it. Very small stones and waste rock are removed there:
The second method of extraction is dredge: a huge floating thing, which is placed in a pre-dug pool with water:
Working hand dredge - escalator with bowls that capture the rock from the bottom of the reservoir:
Then the escalator raises the soil to the top, where the washing factory is also located:
Before you go inside, take a look at how to prepare the sites for permafrost excavation. A year before the dredge comes here, special thermo-needles are thrust into the ground, which defrost the top layer of soil:
Factory inside dredge. The raised breed passes through several sleeves and conveyors:
Along the way she has a mass of different drums and screens, whose task is to weed out all unnecessary. For example, here you can clearly see how large stones are sifted out:
The whole drag is controlled by one person. He sits upstairs and directs the process from the console:
Draghi are very old, many have long been more than half a century. All mining is on the Soviet legacy:
Another example of a dredge:
This is a waste breed that dredge resets. By the "tail" of the channel you can follow the route of the course:
It so happens that the areas where there is gold are removed from each other. In this case, huge excavators are digging a channel for a dredge so that it can swim from one place to another:
The dredge itself does not produce gold, it only produces gold-containing concentrate. Ore gets into a special compartment where the employee dredge does not have access. Once a day, special people come, take out the concentrate, seal it and take it away.
The result of the work per day is eight safes, in which about 4 kilograms of gold will be found:
Gold collectors drive from dredge to dredge on a PAZike:
We did not get to the final analysis of gold from the concentrate, but we were waited by a no less fascinating enterprise. We went to cast gold by hand:
We were met by the mine owner (he is in the photo with suspenders). By the way, the state does not mine, contractors deal with it. However, they are all obliged to hand over the gold found to the state, and not to the side:
Earth, which contains gold, looks like this. It is impossible to find here with a glance, so gold needs to be washed:
To begin with, we take trays and fill them with the rock:
Then we collect some water in the tray. Crush with a hatchet large pieces:
Drain the water with the top layer of dirt, earth and pebbles:
Again, we scoop water, blow it up and drain it. Gold is heavier than earth, so as a result it will remain at the bottom of the tray:
After monotonous and repetitive manipulations in the tray, nothing remains:
We look and see small pieces of gold!
Gold plaque size of about 2 mm. Not thickly, directly say:
After the first success of the expedition members, the gold rush began:
It takes about 20 minutes to rinse one tray, and it’s not a fact that gold will remain at the bottom. Here, for example, it was not found a plaque, but golden sand (in the left corner of the tray):
Of the whole team, I was lucky mainly to one participant, who found two plaques in one tray at once:
Well, now the main thing - what have we done with gold? In fact, we threw it back into the water. Even if the miners see gold on the road, they don’t pick it up. Because it is a criminal article. We did not want the expedition along the Kolyma to end in Mordovia, so we did not risk it, but it was still a feeling to throw gold bars into the water:
