“…2 mol.l -1 HNO 3 was proved to be suitable leaching reducing agent for elimination of heavy metals from the material of sludge bed Slovinky. The possibility of obtaining some metals (Cu, Fe, Zn) from the material of sludge bed was indicated by partial results of monitoring the concentrations of heavy metals in leachate of HNO 3 and it was confirmed by several authors [6,10].…”

Old environmental loads are priority environmental problems in Slovakia. An old environmental load is an anthropogenic constituent in landscape which has its origin in past works (for example mining and mineral processing) but in present time it can also pose risk for the environment. One of environmental loads in Slovakia is sludge bed in Slovinky. Village Slovinky is well-known for mining activities during several centuries. From the beginning copper ore was mined there, later on iron ore which was processed in the metallurgical factory in Krompachy. The mining activity in Slovinky was stopped in 1993. Flotation slurry from ore treatment plant was deposited on the sludge bed which was operated from 1968 to 1999. More than 4.8 million cubic meters of slurry is deposited there. Locality of Slovinky is included in State Remediation Program of Environmental Loads (2010-2015). The paper summarizes the actual state of knowledge about environmental impact of mineral processing and theoretical analysis of problem of environmental impact of environmental load – sludge bed in Slovinky. Experimental part of the paper is focused on study of possibilities of elimination of heavy metals in sludge bed material with the aim of improvement of the environmental quality of surveyed locality.

“…In the case of torrential rains, the stability of the embankment could be disrupted and there could be the danger of an environmental disaster. Because of lack of security, the sludge bed still represents a danger to the nearby town of Krompachy [8]. The Slovinky sludge bed has been studied by several authors from different views.…”

“…Findorakova et al [10] investigated the mineralogical characteristics of the contaminated sediment in the grain fractions by thermal analysis. Angelovicova et al [8] monitored the contents of heavy metals in the soil, the soil reaction, and the species composition of vegetation in the emission field of the sludge bed. Selected water parameters from the stream flowing out of the Slovinky sludge bed were studied by Kozakova et al [11].…”

The Characterization of Slovinky Sludge Bed Material Using Spectroscopic Methods

Slovakia has a long and distinguished tradition in the field of mining and in the processing of raw materials such as gold, silver, copper, and iron ores. In medieval times, the area that is today’s Slovakia was one of the most important producers and processors of sulfide ore, which was processed specifically by flotation. Flotation waste is the remains of fine-grained materials that are deposited in sludge beds after mining and mineral processing activities. Flotation waste also contains residues of heavy metals, which can pose a potential risk to the surrounding environment. The areas with this deposited material (heaps and sludge beds) have been classified as an environmental threat and require regular monitoring by government bodies. The Slovinky sludge bed is one of these areas. The aim of the work was therefore to investigate the selected physico-chemical properties of sludge flotation waste using spectroscopic methods (XPS, XRF, and AAS). Our findings showed that the concentrations of Cu, Zn, and Ni exceeded the limits set by the relevant legislation by several fold even two decades after the end of mining and processing activities. Although the sludge bed material is alkaline, our results showed that the sludge bed material could be a potential source of selected heavy metals. The obtained data could help in the protection and restoration of areas affected by the mining and processing of sulfide ore.
