The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

Because the initial grain size for the supplied biocarbon can reach even 10 mm, therefore, ball milling was used to reduce the particle size. The machine used was the BK2 type ball mill (Metalchem, Łodz, Poland), and the milling time was 24 h; after that, the particle size was reduced to an average of around 1 µm, which is shown in Fig. 1 .
