2013-7-11 The chemical principles of gold leaching by sodium cyanide are the following: 4Au +8NaCN + O 2 + 2H 2 O → 4Na[Au(CN) 2] + 4NaOH The essential requirements for a good gold recovery are adequate cyanide and oxygen levels as well as a p H – value between 10 and 12. The normal cyanide consumption per tonne of ore is in the order of 100 – 500g.

Heap Leaching Heap leaching was introduced in the 1970’s as a means to drastically reduce gold recovery costs. This process has literally made many mines by taking low grade geological resources and transforming them to the proven ore category. Ore grades as low as 0.01 oz Au per ton have been economically processed by heap leaching [4].

Worldwide, heap leaching accounts for about 46% of all gold currently produced, and the rising gold price is making heap leach projects more attractive. A recent study by CostMine focused on the costs and challenges when developing gold heap leach projects. This study looked at 375 projects worldwide that currently recover gold from heap leach ...

2014-10-20 Depending on all the other variables and costs associated, some projects can be viable with a gold grade as low as 0.5 g Au per tonne of ore, with sufficient tonnages. With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached.

2017-8-17 Heap leach gold recovery techniques are employed at Ortiz. Caustic cyanide solutions are sprayed onto crushed rock piles, dissolving the metallic gold from within the rocks and carrying it out as a ‘pregnant’ gold containing solution. The solution is then passed over carbon particles which the gold preferentially precipitates upon.
