  • Gold Cyanidation

    A large outdoors mound of ore is sprayed with a cyanide solution that drips through the rock over time. The resulting liquid is collected at the bottom, and the gold is chemically extracted. Heap leaching extracts less of the gold than processing the ore in a mill, but is much cheaper.

    The solution percolates through the ore, leaching gold as it goes and is drawn off at the base before being treated to recover the gold. In both cases, the gold is recovered from the gold-bearing solution in a process in which pellets of activated carbon made from charred coconut husks are added to the slurry and the gold-bearing ions are adsorbed onto the pellet surface.
