One of the characteristics of Clarabelle Mill is to accept nickel-copper ore from various sources and companies and to produce a nickel-copper concentrate and copper concentrate for further processing. The size of the ore is further reduced in semi-autogenous mills, rod mills and ball mills where all milling is done wet (Fig. 2).

It is typical to find that plants running SAG mills can become capacity-limited in their SAG mills and/or their ball mills depending on the hardness of the ore being processed. However, because sorters can be used to reject barren waste stones, the capacity through both the SAG and ball circuits can be modulated to minimize capacity …
