highest amount of gold in the copper concentrate

Gold extraction - Wikipedia

If the gold can not be concentrated for smelting, then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes.

Copper extraction - Wikipedia

Because a large portion of copper sulfide ore bodies contain silver or gold in appreciable amounts, a credit can be paid to the miner for these metals if their concentration within the concentrate is above a certain amount. Usually the refiner or smelter charges the miner a fee based on the concentration; a typical contract will specify that a credit is due for every ounce of the metal in the ...

Gold processing - Mining and concentrating Britannica

With ores of higher gold content i.e., greater than 20 grams of gold per ton of ore , cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.

For materials containing a relatively high concentration of gold or platinum group metals, the ‘inquartation process’ may be employed.
