The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as nsky-type deposits, hydrothermal deposits, and placer deposits.
Jun 16, 2020 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.
