Much thought and design goes into the making of a heap leach, to derive the best, most economical solution for recovering the gold from the ore. Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution.
