Copper Leaching Method - Metallurgist Mineral

2019-4-19  Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per pound.

Application of SART to Heap Leaching of Gold-Copper

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 of cyanide that are complexed with each mole of ...
