Substantiation of technologies of gold underground leaching from gravel deposits of uzbekistan

Abstract

Studies have revealed that the leaching of placer gold depends on the main geotechnological
factors, the concentration of the leaching reagent, the leaching time, the oxidizing potential of working
solutions, the aggressiveness of groundwater, and the mechanism of interaction of gold with a chlorinecontaining leaching solution is justified.
These scientists developed the first technological schemes of UL landfills, put into practice, and also
calculated the first formulations of leaching solutions that received practical application, studied in
laboratory conditions and proposed the introduction of complexes of technological equipment that allowed
to begin the implementation of the gold UL method in the practice of mining operations.
Despite the large amount of research in the world in this area, the technology of underground leaching of
gold has not been worked out enough, and practically no one has dealt with the leaching of placer deposits in
Uzbekistan.
