Minus 6 in. (150 mm) ore was laid down on the leaching heaps in 5 to 6 m lifts, with a six month leach cycle before a new lift was added above. The top 1 ft (300 mm) of each lift was decompacted by ripping before leaching began. The next stage in heap leaching development, using the concept for gold recovery, was swift to follow.

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.
