Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts.org, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water.Mine Tailings, Tailings in Mining, Gold Tailings Reprocessing . prm usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, prm will apply the method of dry-tailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it.Tailings - Mt Todd Gold Mine Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals.

Similarly, tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs. Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa’s Witwatersrand gold processing operations.Gold mine tailings, the treasure place of recovery gold - prm In 1976, several large tailings of South Africa began to tailings disposal, and has been profitable until now; In a Canadian gold tailings disposal project, a period of processing 50,000,000 tons of tailings, the average grade of tailings is 0.52 grams / tons, and finally, the average recovery rate was as high as 60%.New approaches for extracting and recovering metals from mine . Mine tailings may contain base transition metals, such as iron, copper, nickel and zinc, in relatively high concentrations, and also occasionally precious metals such as gold and silver, in minerals (and native metals) that have been not been separated by froth flotation (e.g. Bryan et al., 2006, Ahmadi et al., 2015).
