Concentration (in ppb) of the “at risk” elements in HTLMix reacted with the mixture of 0.1 M HCl and 0.03 M HNO³ at 100°C and 200°C temperature under 200 bar pressure in Ti batch reactors after 770 hours and 530 hours, respectively (absence of data points reflects concentrations below the limits of detection).
