Ore Processing Challenges in Gold Operation Grinding

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 size.
