Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high. In 2013 the price per gram was around 35 Euros.
In 2015, ore from the mine had an impressive density of grams per tonne, putting it very high on the scale, and potentially the highest grade of gold currently being mined. In the same year, the Macassa mine in Kirkland Lake, Ontario came second, and far below with grams per tonne.
When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
