摘要
Possible soil pollution, as a consequence of dusting of the tailings of copper and nickel ore dressing withdrawn from operation, is modeled. The results show that sulphide-containing final tailing products brought into soil cause rather intensive transformation of heavy metals into water-soluble forms. Thus formed organomineral complexes are stable and yield to no purification with the help of conventional reagents.
