Natural remediation in polluted areas by mining-metallurgical activities. Part II. Revegetation of mining areas.

No more cinder was deposited on the dumb starting with 2004. The environmental balance indicates an overflow of heavy metals admitted in soil that shown a major possible pollution. The wastes mining-metallurgical deposits are a continuous pollution source for environment and human habitat. The physical pollution is manifested through the increase of air-floated and sedimentary powders atmosphere content while the chemical pollution is due to the content of the dumper ash in chemical compounds. The surface water, groundwater, soil, vegetation and the leaving area are the pollution receiver. Also, there is the danger of the West and North flank to debris-slide, the last one with the blocking-up of the river bottom.
