Gold processing 101 Mining Magazine

网页2017年9月7日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

Economic feasibility of responsible small-scale gold mining

网页2016年8月15日Artisanal mining (AM) activities are generally seen as a source of concern owing to their illegality and the environmental pollution that they cause, but in recent years it has been demonstrated that gold mining can be performed on a small-scale mining (SSM) in a responsible way outside of the artisanal dimension. A previous study by the same
