Abstract:This paper provides a summary of the current comminution circuit and its development trend, focusing the discussion on the comminution circuit selection for the No.3 concentrator with 60 000 t / d througput in the Dexing Copper Mine. Based on the large amount of information and data on autogenous grinding tests and conventional grinding practices in the Dexing Copper Mine, the comparison results for various comminution circuits as well as the author's suggestions for the comminution system are presented.
Key words: comminution circuit, high energy crushing, crushing more and grinding less, single stage ball milling
