Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number ofgrinding circuits in parallel, eachcircuittaking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12). Parallel mill circuits increase circuit flexibility, since individual units can be shut down or the feed rate can be …
