## Application of SART to Heap Leaching of Gold Copper

for every kg of cyanide soluble copper extracted. Therefore, if the ore has 40 g/t of cyanide soluble copper, then the minimum quantity of cyanide required for copper leaching is 0.1 kg NaCN/t. 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
