Gold Extraction from Tailings. Star Trace has been providing a standard technique for extracting the mineral contents from the mining tailings. Star Trace will start the process by sample testing through the mineral content of the tailings.

19/12/2019· The mining and extraction of gold from sand are usually carried out at the same time. ... Using the tailings dry stacking system can greatly reduce the water content of the gold concentrate and tailings. And the water discharged can also be recycled. Commonly used dry discharge equipment includes hydrocyclones, dewatering screens, thickeners ...
23/04/2020· In gold sand gravity separation, when roughing with a chute or jig, the coarse concentrate is usually enriched by a shaker with a very high ore ratio, its recovery rate can reach more than 98%, and directly get the final concentrate and abandoned tailings. The above process is generally used in small scale, low grade gold sand concentrators.
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.
