Arsenic release through refractory gold ore processing ...

2021-4-1  Cyanide leaching is the most widely applied leaching process in the case of refractory sulfide ores. Ore concentrates are subjected to cyanide solutions at alkaline conditions (pH ≈ 9.5–10) for 16–48 h, and as a result, gold is extracted in the form of Au(CN) 2-complex.

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 ...
