The head grade of copper in the ore is 12% and the oxidation state is ~60% [ 26 ]. The decision to use the combined technology for processing ores with the ultimate recovery of copper into a bulk concentrate (~90%), its low copper content (~56% copper), and the decrease in copper loss with tailings was taken after numerous tests.
Thus, the lower the operating costs, the lower the grade of ore that can be mined. ... Conventional grinding using a rod mill or ball mill will also be used, or some combination, to grind the ore ...

As can be seen, the product size of the AG mill increases by increasing the ore hardness. Pourghahramani (2012) studied the effect of ore hardness on the product size of the SAG mill in Sungon copper complex, . He observed that hard ore grinding in the SAG mill resulted in more fine products compared to the soft ore milling.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to m. Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate:
