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.

How Is Mining Waste Recycled?

Recycling The Smaller Stuff. Tailings are the finely ground rock left over after mineral processing and they are mostly stored as a watery mix in tailing dams. Despite big improvements in the construction of tailings dams, they can fail, often with disastrous consequences. Some mines reduce this risk by ‘thickening’ the tailings.
