Novosibirsk physicists have developed a unique technology, with which you can capture the tiniest particles of gold that will help to reduce losses during gold mining, its developer, Sergey Afanassenko reported.
"Up to 70% of gold reserves in the crust are gold dust of about 50 microns. This is so-called “river-bar gold" that can’t be caught by miners. It literally "floats" from hands - about 8 tons of gold per year gets the global ocean only from the Amur River,"- said the scientist.
The invention is a centrifuge with a special liquid with nanoparticles. Under the influence of the magnetic field the liquid increases its density, and as a result copper (or other impurities) float to the surface and gold lowers.
