Chemical leaching recovers very small gold particles that cannot economically be recovered any other way. Some mines of that time used chlorine, but chlorine was expensive, hard on equipment and difficult to implement. McArthur's process was not costly to implement and the additional gold it recovered revolutionized.

Intensive Leaching | Gekko

Cyanide leaching is commonly used worldwide for recovering gold from ore slurries or ore heaps. Gekko's intensive cyanide leaching flowsheet advances the output of regular cyanide leaching. Combining higher concentrations of gold or silver with high cyanide and high oxygen amounts intensifies the chemical leaching.
