Abstract
The paper illustrates that the photo-electrochemical pre-treatment of a reagent solution improves the disintegration of a mineral matrix in its following bio-oxidation and the recovery of dispersed gold from the sulfide ores. The laboratory testing of the combined oxidation procedure and the small-scale commercial practice of the electroactivation sorption leaching with the aim to recover dispersed gold from the Koktapas deposit sulfide ores resulted in the 23 % higher recovery of gold.
