Gold processing 101 - Mining Magazine

2017-9-7  At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach 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 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...
