Achievements in Nanomineralogy

Abstract

The results of investigations in the field of nanomineralogy obtained by the Nanomineralogy Sector staff during 5 years (2012–2016) are presented. These include results of researches with the application of high-resolution electron microscopy with microprobe analysis and experimental data. The study objects were unusual grains of placer gold of the Urals, Siberia (Russia), Kazakhstan, and the Yukon Territory (Cana-da). It is concluded that there are nanogold aggregation processes which lead to the formation of globular and “new” gold. These processes may be used in modern technologies of gold extraction.
