Abstract:
A brief informational and analytical overview of gold and platinum content of ore deposits differing in formation, commercial and genetic features, resources and reserves, including magmatic, contact-metasomatic, crusts-of-weathering and metamorphic, is presented. Prominence is given to the problem of gold and platinum content in large and unique deposits of ferruginous quartzites, providing over 60% of the world's iron production and containing independent mineral phases of Au, Pt, Pd, Os, Ru and Ir. Together with technogenic products of their processing they represent a new, unique in resources, non-traditional source of noble metals in the XXI century.
