Abstract

The authors offer a new approach to the actual scientific and technical problem on enhanced efficiency of heap leaching of rebellious oxidized and complex gold-containing ore. The optimization of the leaching technology can be reached through the application of regular shaking and shattering of ore stockpiles by low-density explosive charges.
