Gold Tailings Reprocessing Technology

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. 3. Other minerals recovery from gold tailings.

Gold tailings retreatment offers an environmental solution

Dec 03, 2020· “Gold tailings are materials remaining after extracting the desirable fraction from the uneconomic fraction (gangue) of the ore. Tailings vary, from overburden, which is the waste rock, to other material that encases an ore or mineral body, and which is displaced without processing during mining,” explains Loots.

Application of Hydrocyclone in Gold Ore Tailings

In recent years, hydrocyclones have greatly applied in the beneficiation industry, especially for the tailing treatment. 1.Gold Tailings Filling. At present, most mines use tailings to fill the mined-out area. Tailings need to be desilted (-30-70um) to obtain high concentration (about 70%) tailings sand which also needs special treatment before

Alkali activation as new option for gold mine tailings

Jun 20, 2018· The gold mine tailings (MT) used in the present study include elements such as Mn, As, Cr, Cu, Ni, Zn, Sb, V, and Ba. Particular attention was payed to As and Sb, which can hardly be inertized via most techniques, including geopolymerization, because in an alkaline environment, their anionic forms can occurs ( Fawcett et al., 2015 ).
