It is known that humic substances (HS) are actively involved in geochemical processes of metal transfer in soil and water ecosystems. Humic substances are involved in the formation and erosion of metal-containing minerals and ores. However, questions about mechanisms and kinetics of transfer of mineral-forming metals in soluble form, composition of these forms, mechanisms and conditions for formation of precipitations containing metal in nature, are not fully understood yet. In this paper we are proposing to examine some of these problems by example of iron, which is an important mineral-forming and biologically active metal. Iron is supposed to be included in humic compounds in chelate complexes form, and in highly hydrated oxohydroxo compounds form. Various functional groups present in HS composition can form compounds with iron and stabilize dispersed system. We believe that the same functional groups of HS could also be involved in chemical interaction with dissolved iron compounds contributing to its extraction from solution.
