WASHINGTON STATE DEPARTMENTOF Natural Resources

heap-leach technology has developed significantly over the past 15 years. Use of cyanide heap leaching has steadily increased due to its low cost for recovering gold and silver. Northern Nevada was the site of the first small-scale commercial cyanide heap-leach operation by the Carlin Gold Mining Company in the late 1960s (Hiskey, 1985).

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Application of SART to Heap Leaching of Gold-Copper

If the quantity of copper extracted increases to 300 g/t then the cyanide requirement increases to 0.7 kg NaCN/t. Viewed another way, since the 3 moles of cyanide that are complexed with each mole of copper in the leach solution are effectively “inactive” as far as gold leaching is concerned, the Maricunga heap leach solution is now carrying
