“…Their disposal requires large areas which are mainly productive lands withdrawn from forest resources. Until present, more than 750 000 ha has been disturbed only in the South of the Russian Far East [12]. As a rule, natural landscapes in the waste disposal sites are completely destroyed, and local natural mining systems appear therein.…”

The results of studying mercury pollution of ecosystem in the zone affected by anthropogenic placer gold deposits are given. A major hazard to the environment and human health results from minerals processing wastes polluted with mercury and dumped in the placer gold-concentrating sites (PGCS) near mining villages, which have transformed into unequipped authorized landfills. The recent tendency to their reclamation should favor extensive mercury pollution. Actions have been proposed to ensure environmental safety of mineral processing wastes and reclamation of anthropogenic placer gold deposits.

“…Analysis and generalization of published data [6][7][8][9][10][11] and patent search materials indicate especial urgency of the problem of estimation of the risk of anthropogenic environmental pollution as a result of gold and tin mining. However, available quantitative data on the accumulation and transport of toxic chemical elements in anthropogenic systems in the FEFD are few in number [6,[8][9][10][11].…”

“…However, available quantitative data on the accumulation and transport of toxic chemical elements in anthropogenic systems in the FEFD are few in number [6,[8][9][10][11]. The problems related to assessment of environmental pollution due to placer gold and tin-ore mining, protection methods, and environmental monitoring both in the FEFD and in Russia as a whole turned out to be poorly studied [6][7][8].…”

“…While estimating wastes from placer gold and tin ore processing (including those from the placer gold concentrating plant and tailings dump) [6,11] as a source of environmental pollution, it should be kept in mind that these wastes have long been accumulated as piles within the mining village area; for instance, the placer gold concentrating wastes have been stored for more than a century. The major part of the heavy fraction therein is represented by magnetite, hematite, sulfides (pyrite, cinnabar, in some cases, halenite).…”

The necessity of local environmental monitoring of ecosystems polluted by wastes from gold placer and tin ore deposits has been substantiated by considering former Sofiiskii gold placer mine and Solnechnyi ore-dressing and processing enterprise (Far Eastern Federal District). The results of studying their negative effect on the biosphere have been discussed. Principles of local environmental monitoring have been developed with account taken of specificity of anthropogenic flows generated during gold and tin extraction processes.

The paper considers some ecological problems of the gold-mining enterprise in Amurskaya Oblast’. The investigations have revealed the technogenic pollution of the soil-grounds, air basin, and vegetation under the action of the processing wastes. High concentrations of heavy metals were found in the soils and vegetation in the zone of influence of the plant processing heavy concentrates at a distance of 100 and more meters. They are 2 to 90 times higher than the background values practically in all directions from the technogenic object. High TM concentrations were found also in the soils of building zone. Using the innovation approach we have elaborated the measures for decreasing the pollution negative effect on the habitat. We propose a new way of reclamation of the lands disturbed by the wastes of the mineral raw material processing with the use of the mixed bark-compost of the forest industry wastes.
