Abstract
The authors describe experiments on pretreatment of ore by injection of explosive gases before underground leaching of gold in mine conditions. It is shown that injection of explosive gases into opening micro-fractures enhanced efficiency of underground leaching owing to microstructural transformation of ore containing dispersed gold.
