Gold Tailings Reprocessing Technology

The gold tailings after cyanidation are dealt with tailings dry stacking method. It 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. For other elements in the gold tailings, Xinhai applies magnetic separation, flotation and other methods to deal with

From Tailings to Treasure? Miners Make Money Reprocessing

07/05/2015 DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.

Re-Processing Gold Tailings in South Africa

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- deposited in a new area far from urbanization, allowing

Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990). Gravity and magnetic separation techniques are also used to win

Minerals Free Full-Text Gold Mine Tailings: A

Mining of minerals such as gold, copper, and platinum has been one of several activities sustaining the economy of South Africa. However, the mining sector has contributed significantly to environmental contamination through the improper disposal of mine tailings which covers vast areas of land. Therefore, this study utilised a vitrification process to manufacture glass from gold mine tailings.
