“…The known nonstandard methods to analyze gold-bearing raw materials, developed in USA and in Russia [3], enable reliable detection of chemically bound nano particles of noble metals in natural and manmade-transformed minerals. The integrated mineralogical, geochemical and geotechnical research of samples taken from gold placers in Transbaikalia, as well as from dredging and sluicing tailings, and from gold washing sludge often revealed chemically bound gold [4,5]. It is also frequent that gold occurs in bimetal gold-silver bullion [6].…”

The Transbaikal Region holds a large stockpile of gold reserves in placers. Gold placers differ in structural tectonics, morphology and parameters of productive strata, their specific mineralogical and geochemical composition, grain-size composition and shape of gold grains, roundness and fineness of gold particles, etc. The drop in the gold content and thickness of productive sand at placers being currently mined necessitates studying refractory gold, including encapsulated, dispersed and chemically bound gold. This article discusses new patent-protected methods for identifying nanoscale gold. New geotechnologies for gold extraction from placer sands using solutions with active chloride complexes pumped into productive formations via wells are presented. Alongside with pumping out pregnant solutions, it is proposed to use the electro-diffusion deposition of dissolved gold from a conventionally immobilized pore solution onto ion-exchange resins placed together with submersible cathodes in wells.

“…It is possible that these minerals-concentrators hold such atomic clusters and clusters of gold as: (Fe,Au) -Au 2 S 2 Au 2 SiO 2 , Au 2 SiO 4 and Au n Si m , which are metastable and may change from the cluster form to the atomic cluster form and backward: (Fe,Au) -Au 2 S 2 = (Fe,Au 3 )S 2 .
