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 reaction to maximise mineral recoveries.
