this usually means sacing some gold recovery. The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle

Over-grinding does not have a significant benefit to gold recovery but reduces the mill throughput and results in higher unit costs in terms of energy, grinding media and reagent consumption. If there are frequent changes in ore hardness, grinding circuit performance is affected and poses challenges for operators to maintain the target particle ...

Costs in the gold mining industry increased for the second consecutive quarter in Q1'21, with the global average All-in Sustaining Cost (AISC) up by 5% q-o-q to US$1,048/oz, reaching its highest level since Q2'13. This, combined with a 4% fall in the average quarterly gold price, resulted in a 14% drop in AISC margins (the gold price minus AISC) between Q4'20 …

The costs associated with power supply, grinding media, and liners used in comminution circuits almost always represent the single largest cost in gold extraction processes (Mosher, 2005). Thus, the efficiency of the entire processing operation is largely dependent on the efficiency of the comminution circuit.

COSTS ON THE RAND. The distribution of costs at Randfontein Estates Gold Mining Co., which is typical of the older sand-slime type of plant, is shown in Table 100.
