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

Different ore embedding forms, gold particle size and form have certain influence on the determination of grinding fineness. Take a gold mine as an example. The natural gold in this gold mine has a relatively fine particle size and is fine-grained gold. The 0.037-0.01mm part accounts for 56.32%, and the part smaller than 0.01mm accounts for 36.80%, which are inter-granularly embedded in ...
