Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energy-intensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
The equivalent circuit depicted in Fig. 4c was used to fit the impedance spectra in Fig. 9a whereby R e represents the solution resistance, C c is the surface capacitance, and R ct is the charge transfer resistance which is attributed to the electrochemical corrosion rate. The equivalent circuit in Model c is employed to characterize bioNCs.
