Hydrometallurgical method of processing the tetrahedrite concentrate from Maria Mine in Roznava, Slovakia

This paper summarizes research results obtained under pilot-plant conditions at Rudnany (Slovakia). Results made it possible to change some technological parameters that have been indicated in the new linear flowsheets and are depicted in the figures. These changes were followed by other research projects funded in the framework of VTP scheme of applied research of the Slovak Ministry of Education that have been implemented at the Faculty of Mining, Ecology, Management and Geology at the Technical University of Kosice between 2001 and 2007. Extensive research material covering both laboratory and pilot-plant investigations that were carried out at the Institute of Geotechnology of the Slovak Academy of Sciences and the subsequent above-mentioned research can be obtained from the author of this paper.
