Abstract

This thesis deals with the treatment of waste material produced during gold-bearing ore mining by leaching method. Thiourea was used to leach, which can dissolve gold and is considered one of the alternative methods of leaching. The thesis also deals with strategic raw materials, occurrence of gold and its forms. Furthermore, the thesis mentions methods that are used in the world to treat gold-bearing ore in order to obtain gold. In the experimental part is verified the leaching of gold bearing samples from the Slovak locality Hodruša-Hámre (Slovak Republic). The aim of this work is to monitor the decrease of gold in the samples compared to the gold content in the input material when determining the pH and temperature.
