Technologie úpravy zlatonosných rud

Abstract

The topic of this thesis was Technology of Gold Ores Dressing. The first three chapters of the theoretical part deals with a general description of the importance of gold for human society, gold usage, the chemical and mineralogical characterization characterization of gold and presence additive in minerals . Next part focuses on deposits and gold mining in the Czech Republic, in the world and a description of the investigated locality from which comes the material used for the experiments. The fourth chapter contains methods for processing of gold which help to get high quality concentrates from gold deposits. The experimental part of the work was focused on laboratory experiments that have been conducted in this thesis. The aims of this chapter were to evaluate the best flotation collectors, verification the effect of speed on the yield of concentrate, clearing flotation (gain the highest quality concentrate), verification hydrophobicity of gold and the gravity separation method using centrifugal forces.
