URI: https://data.geoscience.earth/ncl/ProcessingActivityType/cyanidetankLeaching
Cyanide leaching is most common in processing gold (and silver) ores. Cyanide dissolves gold from its host rock providing the ore exists as an oxide and is not bound closely. Low-grade ore contains gold in the form of microscopic particles and is processed via heap leaching. If gold is present in a larger and more concentrated state, the ore is ground finely and leached in a tank. A gold/cyanide complex forms as the gold dissolves from the rock or pulp (finely ground ore), according to the equation: 4Au + 8CN– + 2H2O +O2 –> 4Au(CN)2 + 4OH–
