Mar 14, 2012· Near Flin Flon, , Satori Resources of Toronto has already recovered some gold from the milling equipment at the Tartan Lake gold mine. An initial 79.9 oz of gold and 4.61 oz of silver were recovered from 2.46 tonnes of material. The mill cleanup will continue, but the company also plans to reprocess the tailings this year.
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.
Let's take a look at some reprocessing projects around the world: West Rand Tailings Retreatment Project (WRTRP) in South Africa Through a combination of tailings storage facilities, the company estimates there to be 6.2 Moz of gold and 97.2 Mlb of uranium.
The average gold extracted between the surface tailings and 1m deep tailings within just 5 h reaction time is 73.9 % for thiosulfate leaching and 73.4 % for cyanide leaching.
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-

There is also a growing awareness that there is a potential of realising ... The gold tailings samples for the test work were sourced from various mining locations in SouthAfrica as shown in Table 1. The samples ...
Iron tailings: the iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings.

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.
A typical flow sheet for the reprocessing of tailings is shown below in figure 2. Figure 2: Simplified diagram showing the hydraulic re-mining of tailings It can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste, mine the waste as a product, or for moving of the tailings to a more suitable location.
