At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bioleach costs are at least 200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around Clearly this is a function of gold price, but in the current gold price and cost ...

Gold processing Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by ...

CIL (Carbon In Leach) is the carbon leaching method for gold extraction. Normally the CIL process can concentrate gold from g/t in ore to 2000 to 6000 g/t on carbon. CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content. It is characterized by low cost, short infrastructure construction time and few production links.
