ABSTRACT

The gold deposit in Zlaté Hory region has been known since the middle ages when the first mention about gold-washing and gold-mining had been appearing from the thirteenth century. Later on, the amount and quality of ores enabled also development of underground mining of gold but also mining of another ores such as Cu, Pb and Ag. The new age history started in 1965 on the deposit Zlaté Hory – south, when the mining was expanding to another localities as well. Termination of mining dates back to 1992. A wastewater slim pit was set after this mining and further modification. No modification is of such a quality that it would be possible to guarantee complete contraction of useful components. Due to new findings and facilities it is possible to apply on these materials another methods and machines due to which we could recontract lost gold. The first part of the thesis is focused on a general description of the locality and used methods of separation. Furthermore, the article characterizes the material from the mineralogical as well as granulometric point of view. Following these passages there are results that were reached by means of gravitational separation. The first findings show low content of gold in the supply material, however by means of applied gravitational separation of centrifugal powers it is possible to obtain concentrates with high content of gold. The thesis represents and suggests one of ecologically acceptable alternatives for processing of gold bearing materials in the region of the Czech Republic.
