Main geochemical problems concerning the environment and mining industry interrelation are connected with the
transformation of natural water chemistry by mining wastes. The investigation of many mines in Primorye, the southern
part of the Russian Far East, showed that their mining waters have high concentrations of heavy metals and aluminium.
Water acidity is primarily connected with the amount of acid-forming sulphide minerals in ores and also depends on the
neutralising capacity of rocks. Considerable quantity of metals occur in the waters in dissolved form. Metal
concentrations in mining waters exceeds the natural levels by 2-5 orders of magnitude and can't be reduced to the
background levels even after multiple dilution. It is necessary to develop and put into practice new technologies so that to
reduce the geochemical impact upon the environment.
