Abstract

The article presents the results of a study of the qualitative and quantitative analysis of metal ions in the bacterial oxidation of flotation concentrate in the liquid phase by mass spectroscopy. Changes in the concentration of metal ions (Na, Si, K, Ca, Fe, etc.) and ions of noble metals (gold, silver) in the process of bacterial oxidation of flotation concentrate were determined and changes in their concentration in the process were substantiated
