Laboratory Leaching Tests to Investigate Mobilisation and Recovery of Metals from Geothermal Reservoirs

Figure 16

The amount of “at risk” elements in leachate samples reacted with 0.1 M acetic acid at 250°C temperature under 250 bar pressure in ppb after 36, 37, 42, 27, 38, and 48 minutes, respectively (absence of data points reflects concentrations below the limits of detection).
