cyanidation gold intensive

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

Concentrates are leached under intense conditions with high cyanide levels from 3000 ppm up to 50000 ppm and oxygen levels maintained above 15 ppm DO Typical leach times range from 6 hours up to 24 hours Overall average recoveries are generally above
