Gold and pathfinders metalloorganic forms in podzol soil at the area of Novye Peski gold deposit (South Karelia)

Abstract

Gold and natural organic matter interaction, including the interaction with humic and fulvic acids, is the most important part in migration and precipitation of that chemical element in supergene zone. Research into elementorganic forms of gold and related elements, which are often associated with gold deposits (As, Cu, Ag, Ni, Zn, Pb, Te, Bi, Se, Mo, Sb), allowed us to learn the groups of elements bounding preferably to one or the other humus acids and the most enriched with that element’s soil horizons. Complexation of gold and nickel are with both humic and fulvic acids; zinc, silver and antimony bound preferably to humic acids, arsenic and copper — with fluvic acids. More detailed research of different mobile forms of gold in soil profiles allowed us to identify the features of gold forms related with the type of soil horizon and location of soil profile in relation to the ore zone.
