How to Extract Gold from Tailing?-mining-pedia

Mar 22, 2021 Extracting gold from tailings is one of the effective ways for its resource utilization. After roasting-cyanidation process, most of the gold in the tailings is embedded in the iron oxide inclusions and silicate (quartz) inclusions. Fully open these two inclusions is the first condition to obtain a higher gold extraction rate.

From Tailings to Treasure? Miners Make Money Reprocessing

May 07, 2015 DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013.

Gold Tailings Reprocessing Technology

Xinhai usually adopts the all-slime cyanidation + CIP in the gold extraction from old tailings. The gold tailings after cyanidation are treated by dry stacking. That is a technology that recycles the filtrate to realize the water resources recycling in processing plants with pressure filtration process, and get rid of most cyanide in the tailings.
