Gold Tailings Reprocessing Technology

In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity and low-grade gold tailings is common heap leaching.
