Sep 11, 2014· The gold and silver tailings were generated from conventional mining operations between 1992 and 1999. The original mining operation's recoveries were poor (< 30%) and considerable amounts of ore were placed in the dam. The dam has an estimated 5,137 million metric tonnes of ore, grading 3.8 g/t gold and 38.6 g/t silver.
Drilling undertaken in 2014 showed an average grade of .043 oz/t or 1.47g/t, supporting the development of a system to re-process the tailings. The initial design and testing took place over 2015 and 2016 with the first gold pour coming from the tailings re-processing project in July of 2016. True North Tailings Mineral Reserves:
The barren slurry, now known as tailings, is pumped to the tailings storage facility (5). In contrast, by the time the carbon reaches the first adsorption tank it has recovered most of the gold and silver from solution. This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water.

These filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001). This type of tailings storage produces a stable deposit usually requiring no retention bunding and is referred to as 'dry stack'.
Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
The mining process generates two byproducts: Waste Rock: rock that is non-mineralised, or mineralised rock which contains insufficient gold to process economically Tailings: the slurry that remains once the gold and silver have been extracted from the crushed ore at the processing plant
It is estimated that the tailings dam of the Mouteh Gold Mine, in , contains more than 770 kg of gold. Microscopic analysis reveals that sulphide minerals and active carbon are the main ...
Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said "There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt ...

A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.
If you really want to understand how to invest in gold mining companies, you have to ... This process separates the gold from impurities (slag) so that it can be poured into bar-shaped molds ...
The breach of a tailings pond at the Mount Polley copper and gold mine in B.C. has released 10 billion litres of mining wastewater into local waterways in early August.
What are tailings dams? Tailings dams are used to store water and waste that come as by products from the mining process. It is estimated there are at least 3,500 tailings dams around the world. But as there are around 30,000 industrial mines, the number of tailings dams is likely to be much higher.
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
