The paper presents the results of the research on the intensification of the cyanidation process of low sulphide gold bearing ore from the Burgunda deposit with relatively simple material composition. To intensify the process, it is proposed to conduct comparative research on three methods: direct cyanidation and cyanidation in the grinding cycle, including the supply of oxygenated recycled water. The results of the kinetic research showed high efficiency of the third method - cyanidation in the grinding cycle with supply of recycled water pre-saturated with oxygen up to the concentration of 15.8 ppm. It made it possible to achieve both high levels of gold recovery and transition of the gold dissolution rate to the kinetic range.
