The waste products of the ore mining and processing industry usually dispose to the landfield where wastes are oxidized by atmospheric oxygen and microbial activity in the presence of water, forming acid mine drainage (AMD) with high concentrations of SO42-, Fe, Al, Zn, Cu, Cd, Pb, Ni, Co, Cr and other elements (Nordstrom and Alpers, 1999; Lottermoser, 2007; Nordstrom, 2011). Acid mine drainage is the largest environmental problem facing the world mining industry.

The given work focused on solving the fundamental problem of environmental geochemistry and material science related to developing a new environmentally safe and cost-effective technology for AMD remediation and extraction of strategically important metals using new alkaline humic agent derived from peat. A liquid peat-humic agent (PHA, Bogush and Voronin, 2011) was developed by chemical (alkaline hydrolysis), mechanical and thermobaric treatment (using hydrodynamic cavitation) of peat from the Krugloe deposit (Novosibirsk region, Russia).

A novel cost-effective and environmentally friendly method to remove metals from acid mine drainage was developed using modified peat with subsequent thermal treatment (patent N2011139274, RU). This new technology can solve two problems: 1) effective treatment of AMD from potential pollutants (e.g. Zn, Pb, Cu, Cr, Ni, Cd, etc., 70-99% recovery) and production of treated water which can be used in mining industry; 2) extraction of strategically important metals (Cu, Zn, Pb, Ni, Co, Ag, Au, etc.) from AMD.

This research was financially supported by the Russian Foundation for Basic Research (grant 11-05-12038-ofi-m-2011) and OPTEC LLC.
