Summary:Title screen
More than eighty years of mining at the Novo–Ursk Au-bearing sulfide field (Kemerovo region, Russia) have produced a mixed natural–industrial system “wastes–gold-bearing acid mine drainage (AMD) waters–peat”. The behavior of Au, Ag and related elements in the system “wastes–AMD” is described in Part 1 of our study (Myagkaya et al. 2016) where we discuss interaction between the gold-bearing mine drainage waters and peat. This interaction leads to rapid accumulation of Ca, Fe, Mn, Ba, Cu, Zn, Se, Au, Ag, Hg, Pb to concentrations exceeding those in cyanidation wastes (especially, Cu, Zn, Se, Hg, and Pb). The contents of Au (about 5 ppm on average, locally as high as 155 ppm) and Ag (average about 11.2 ppm, locally up to 560 ppm) in peat are above the lowest economic values. These results provide clues to technologies for both generation of secondary gold (silver) deposits at existing or planned tailings and immobilization of toxic elements.
