In addition to groundwater flow, the FEFLOW model also considers mass to simulate the transport of lithium. Specific model parameters such as longitudinal and transverse dispersivity were defined as follows: longitudinal dispersivity was set to a constant value of 20 m and the horizontal and vertical transverse dispersivity values were set to 10 m. In addition, unwinding process is activated. The effective porosity for the mass transport simulations was based on the conceptual specific yield and consistent with the value used for the resource estimate as it is shown in Table 71.
The initial concentration of lithium for the simulations was based on resource model (Section 14) and is shown in Figure 137.
