As shown in Fig. 2, when the gold concentrate is leached after wet grinding, the concentration of copper ions in the solution is significantly lower than that of the system leached after dry grinding.Within an hour, the copper ion concentration in the solution lost nearly 70%. This means that the slurry system after wet grinding is not conducive to the stable existence of …

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
