When tailings deposition ceases, there will be an initial period in which the water quality within the pond will require monitoring and treatment. During this time, the tailings pond will be pumped to a low level to assist the tailings surface to gain strength. Tailings Storage 2 was decommissioned for tailings deposition in 2005.
In 2002, before the construction of new tailings pool, the gold tailings in the old tailings pool was over 900 thousand ton. The gold content was about 1,665kg, while silver content was about 25t. Xinhai practice tailings re-processing line in pulp-in-carbon factory, capacity was 300t/d, recycled gold and silver by using Gold CIP Production Line.

Another possible process to recover the gold lost in the table residues is cyanidation. A sample of the tailings of flotation test F9, containing 2,63 g/t PM and 96.3% – 200 mesh, has been cyanided in a solution containing 10 %, solids, 0,5 % NaCN and 0,5 % CaO.
Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, xinhai 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.
historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-
