People are fighting for metal, but it is everywhere. In the sand, water, and even dirt. For example, the Ob river, according to estimates, each year carries its flows not less than 8 tons of gold. But to remove it is not so easy. Sergei Afanasenko, CEO of the company to extract fine gold: "70 percent of all gold on Earth – gold is very small, thin and dust." Scientists from the Academic struggling with the problem of extracting this gold dust for several years. They have created devices allows you to capture very tiny particles – five microns. Recently, for the sake of experiment, scientists took a little river mud in the rivers Biya and Katun and turned it into a concentrate containing gold, 3 kilograms per tonne. Vladimir Prohortsev, the main constructs of the enterprise to extract fine gold: "From mud to extract gold impossible. You can get gold-bearing concentrate, which then requires further processing. But the real Klondike – a process dumps, called tailings, which remain in the gold mining companies. Such deposits throughout the country thousands. Sergei Afanasenko, CEO of the company to extract fine gold: "Our research showed that if the extract gold is less than 100 microns in the traditional ways of processing, then lost 80-90%. To somehow cope with this problem, we devised a centrifuge, which can increase the force of gravity at 50, 100 times. That's gravity, or rather pseudo-gravity allows you to highlight the gold without the use of toxic mercury and cyanide. Another ingenious way – liquid separation. Here is unremarkable black liquid are actually nanoparticles, dissolved in kerosene. Put it in a magnetic field, and it becomes thick and feels like an elastic rubber. It can now swim heavy metals such as lead or tungsten. This liquid is used for extraction and separation of gold. Installation, created by scientists of Akademgorodok already operating successfully throughout the world. To technologies that would allow from tap water or dirt to dig for gold on an industrial scale – a single step. All Regional News
