2. Background. The SAG grinding process has been modeled by various authors, either generating explanatory models of the grinding process, with the aim of modeling, simulating, and optimizing the individual process, as well as integrating it into aggregate processes, such as the mine-to-mill (M2M) paradigm, a practice that has generated the …
Compared to the simulation under RCP4.5_2020, the result of RCP4.5_2080 simulation showed a less variation in copper concentration. However, the enhanced rainfall by climate change increased the river flow which diluted the aqueous concentration of copper and reduced the concentration in the sediment as well as the health risks for the humans.

In the other areas, the flow dynamics of the concentrator were investigated using numerical simulation. [Citation 32] The effect of centrifugal force and fluidization water pressure on the fluid velocity component was considered (Figs.6 and 7). The gradient characteristics were revealed by analyzing the turbulence intensity in the radial direction.
