Starting with simple binary systems (one cation + one anion + water), quinary and hexary systems were also examined. The theoretical part of the training course was supplemented by a laboratory practical. During this, salt solutions were prepared, dissolution processes in these solutions were specifically initiated, and the ion concentrations were analysed.
The course concluded with numerical calculations of ion concentrations in salt solutions using PHREEQC (a numerical solubility equilibrium calculation programme) in combination with THEREDA (a solubility equilibrium database), and their application to specific case studies. The pleasant learning atmosphere in the course, with plenty of opportunities to ask questions, facilitated effective knowledge transfer, enabling participants to gain a comprehensive understanding of the formation of salt deposits and the mining implications arising from the contact between the solution and the host rock, salt.
