ccording to Environment Report 2004, eight main areas with most violated environment can be identified in Slovak republic. Among those areas are also regions with mining and raw mineral processing, e.g . Jel\vsavsko -luben\'\icka, Rudniansko-gelnick\'a, Ko\vsicko-pre\vsovsk\'a a Zempl\'\inska regions. Affected regions can be defined by individual environment component grade, risk evaluation and regulations focused on environment protection. The presented paper deals about environmental impact of business activitie...

Geochemical prospecting is one of the most useful methods in mining deposits exploration. For most of minerals and elements, geochemical data are reliable and helpful. As these methods are not expensive we can use theme in large scale. But non of these methods ( based on sampling from rocks, stream sedimentary, soil, water etc.) are complete and need complementary methods such as heavy mineral study, geophysics, remote sensing etc. Heavy mineral study is one of the best complementary methods. Based on this method ...

Multivariate analysis is one of the base stage in heavy geochemical prospecting (heavy mineral study). Factor and clustering analysis identify different type of mineralization and the relation between minerals in studied area. But in these methods for each mineral it is necessary to be at least 10 valid samples. Therefore some minerals can’t be analyzed by such methods and we miss some minerals in multivariate analysis and can’t identify the relation between these minerals and others. Jaccard coefficient can b...
