Slovak republic committed to implement into legislative direction of European parliament and European Council 2006/21/ES from March of 15th of 2006. The direction contains conditions about disposal with wastes of mining industry, which changes and adds direction 2004/35/ES. This legislative required creation of complex evaluation methodology of different types of mining wastes. Tailing pond represents area for permanently or temporary deposition of mainly hydraulically consigned mud/sediment (waste). Consigned mud...

Sb-mineralization had been exploited in many localities in Slovakia. Contamination of environment by Sb, As and other heavy metals is specific problem of Slovak mining regions. Three localities Poproc (in eastern part of Slovakia), Medzibrod and Dubrava (in The Low Tatras) are abandoned mining areas where the stibnite ores had been exploited for many years. These areas represent high potential environmental risk because of transport and accumulation of contamination in different parts of environment (waters, strea...

Sb-mineralization had been exploited in many localities in Slovakia. Contamination of environment by Sb, As and other heavy metals is specific problem of Slovak mining regions. Natural background for groundwater in Slovakia was appointed to 1 $\mu$g/l for Sb and 5 $\mu$g/l. Two localities Poproc (in eastern part of Slovakia) and Dubrava (in The Low Tatras) are abandoned Mining areas where the stibnite ores had been exploited for many years. These areas represent high potential environmental risk because of transpo...

Environmental large-scale contamination in surrounding of abandoned Sb-deposits in Slovakia by toxic elements (Sb, As, Zn, Pb, Cu...) as result of long-time mining activity is still undiscovered field. Surroundings of abandoned antimony deposit Popro\vc bear high concentrations of toxic contaminants mainly of sulfide relative minerals. Pollution resulting from long-time mining activity was observed in area adjacent to adit Agnes showing Sb concentrations within values 4 700 – 10 000 mg.kg-1 and maximum As concen...

Antimony mineralization has been intensively exploited at numerous deposits in Slovakia from 17th century until a while since. Weathering and dissolution processes in the environment of mine tailings and closed mines, mobilize elevated levels of toxic elements such as arsenic and antimony, which represent dangerous contaminants for the surrounding ecosystem. The problem of contaminated groundwater should be solved and one of the possible remediation method is the Permeable reactive barrier system (PRB). The choice...
