The extraction of rock salt, potash salt, trona and other mineral raw materials in solution mining has clear advantages over conventional mining: Brine technology is not only cheaper but also safer. Costly pit construction is not required either, and the number of personnel is much lower. The raw materials obtained are used in many different ways: Brine can be processed into table salt or de-icing salt, it can be used in the chemical and pharmaceutical industries or for the production of fertilizers.

Exploratory drilling, resource calculations and cost-effectiveness considerations provide the basis for deciding whether a brine extraction project can be implemented. Technical planning refines the picture. This enables operators who want to market a high-quality product to plan for the long term.

Salt caverns in solution mining require highly differentiated knowledge. Even if salt dissolves perfectly in the lab, ideal rock composition or mineral concentration cannot be expected in nature. Geological conditions provide the framework and chemical, physical and thermodynamic factors influence how intensively the deposit can be used and what residues are produced and in what quantities. Both a suitable brine process and careful solution process planning are critical to the profitability of an operation and to the product quality.

That is why DEEP.KBB also uses a comprehensive, interdisciplinary approach in solution mining: Using 3D computer simulations, geoscientists and engineers work together in the lab to develop an extraction process that is optimally adapted to the respective deposit.
